Description

Technical Field

[0001] This invention relates to the field of thermal spraying technology, and more specifically to a device and method for collecting dispersed single flat particles on the surface of a thermal spraying substrate. Background Technology

[0002] Thermal spraying involves heating fine, dispersed metallic or non-metallic coating materials to a plastic or molten state, then accelerating them with compressed air, causing a constrained stream of particles to impact the substrate surface. The impacted particles deform under pressure, forming stacked flakes that adhere to the prepared substrate surface. They then cool and accumulate, eventually forming a layered coating. Therefore, the formation process of the basic structural unit of the coating—the "flat particle"—directly affects the coating's structure and properties. The size and morphology of the flat particles determine the layered structure of the coating; the higher the degree of particle spread on the deposition surface, or the higher the degree of particle flattening, the denser and higher the quality of the coating. Since individual flat particles cannot be observed in the coating, various devices have been invented to collect them from the substrate. The literature "The Influence of Reynolds Number on Droplet Flattening Behavior in Plasma Spraying" (Journal of Inorganic Materials, 2014, 30(1): 65-70) uses a slit method with a slit baffle in front of the substrate to collect flat particles. The literature "Study on the Pore Formation Mechanism of WC-10Co4Cr Coating Based on Particle Flight Characteristics and Spreading Behavior" (Journal of Inorganic Materials, 2018, 33(8): 895-902) and "Influence of HA Powder Particle Size on the Morphology of Flat Particles and the Microstructure of Coating in Micro-beam Plasma Spraying" (Surface Technology, 2019, 48(4): 91-96) uses a small circular hole lattice baffle to collect flat particles in front of the substrate. The literature "Knowledge Concerning Splat Formation: An Invited Review" (Thermal Spray Technology, 2004, 13(3): 337-360.) and "Influence of Substrate on the Formation of Mo Layers in Plasma Spraying" (Thermal Processing Technology, 2007, 36(3): 53-56) uses a shutter-type device to collect flat particles in front of the substrate. Regardless of whether a slit baffle, a small circular aperture baffle, or a shutter device is installed in front of the substrate, the presence of the baffle and shutter device will inevitably change the environment surrounding the particles when they collide with the substrate, making it different from the actual environment of the particles during spraying. In addition, some methods use a small substrate clamped at one end of a rod, and during the spraying process, the other end of the rod is held to allow the substrate to quickly sweep across the flame to capture individual flat particles. This method inevitably makes it difficult to control the distance between the substrate and the nozzle. Summary of the Invention

[0041] Embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While some embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the invention. It should be understood that the accompanying drawings and embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the invention.

[0042] It should be noted that the concepts of "first" and "second" mentioned in this invention are only used to distinguish different devices, modules or units, and are not used to limit the order of functions performed by these devices, modules or units or their interdependencies.

[0043] like Figure 1 As shown, this invention discloses a device for collecting dispersed single flat particles on the surface of a thermally sprayed substrate, comprising a substrate 100, a substrate movement component 200, and an impact component 300. The substrate 100 is used to collect dispersed single flat particles. The substrate movement component 200 includes a first guide 210, a second guide 220, and a pusher 230. The substrate 100 is disposed between the first guide 210 and the second guide 220 and is movable from a first position to a second position along the first guide 210 and the second guide 220. The pusher 230 is connected to the substrate 100 and is used to push the substrate 100 from the first position to the second position. The impact component 300 generates an impact force and transmits the impact force to the pusher 230, causing the pusher 230 to push the substrate 100 from the first position to the second position.

[0044] This invention generates an impact force through the impact component 300, causing the pusher 230 to rapidly move the substrate 100 from the first position to the second position along the first guide 210 and the second guide 220. The thermal spraying gun is positioned directly above and perpendicular to the path along which the substrate 100 moves from the first position to the second position. The spraying flame of the gun is located on the path between the first guide 210 and the second guide 220. Under the action of the impact force, the substrate 100 rapidly passes through the spraying flame of the gun, thereby collecting and dispersing individual flat particles. The thermal spraying substrate surface dispersion individual flat particle collection device of this invention avoids the problem of setting a baffle or shutter device in front of the substrate affecting the spraying flame environment and resulting in a large difference between the obtained individual flat particles and the actual particles during spraying.

[0045] like Figure 1 As shown, the thermal spraying substrate surface dispersion single flat particle collection device also includes a base plate 400. One end of the first guide member 210 is located at the upper part of one end of the base plate 400 and is fixedly connected to the base plate 400. The other end of the first guide member 210 extends to the outer side of the upper part of the base plate 400. The second guide member 220 is arranged parallel to the first guide member 210. One end of the second guide member 220 is located at the upper part of one end of the base plate 400 and is fixedly connected to the base plate 400. The other end of the second guide member 220 extends to the outer side of the upper part of the base plate 400.

[0046] In this embodiment, the material and surface treatment of the substrate 100 are the same as those of the actual sprayed workpiece. The first guide 210 and the second guide 220 are guide rails, which are made of 45# steel. One end of each guide rail is fixed to the base plate 400 with an M5 screw, and the other end extends to the outside of the base plate 400. The spraying flame is located between the first guide 210 and the second guide 220 on the outside of the base plate 400. With nothing obstructing the spraying flame and altering the spraying flame environment, the collected individual flat particles more closely resemble the actual spraying conditions, making the experimental research more accurate and reliable.

[0047] like Figures 1 to 3 As shown, the pushing member 230 includes an impact rod 231 and an impact rod sleeve 232. The impact rod sleeve 232 is fixed to the upper part of the base plate 400. One end of the impact rod 231 passes through the impact rod sleeve 232 and is connected to the base 100. The impact rod 231 and the base 4 can be fixedly connected or contact connected. Its main function is to transmit the impact force to the base 4, so that the base 4 can move quickly along the first guide member 210 and the second guide member 220. The other end of the impact rod 231 is used to receive the impact force applied by the impact assembly 300.

[0048] The impact rod 231 can be made of 45 steel with a diameter of 10mm, and the impact rod sleeve 232 can also be machined from 45 steel. It is fixed to the base plate 400 by four screws with a screw hole diameter of 6mm. The diameter of the horizontal hole through which the impact rod 231 passes is adapted to the diameter of the impact rod 231 so that the impact rod 231 can slide freely in the horizontal hole. The diameter of the horizontal hole can be set to be slightly larger than 10mm, or a linear bearing can be installed in the horizontal hole. The inner diameter of the linear bearing is adapted to the outer diameter of the impact rod 231 so that the impact rod 231 can slide freely in the linear bearing.

[0049] The impact assembly 300 includes a column 310, a pendulum 320, and a pendulum shaft 330. The column 310 is fixed on the upper surface of the base plate 400, and the length direction of the column 310 is perpendicular to the upper surface of the base plate 400. The pendulum shaft 330 is fixed on the upper part of the column 310 in a direction parallel to the upper surface of the base plate 400. One end of the pendulum 320 is hinged to the pendulum shaft 330, and the pendulum 320 can rotate along the pendulum shaft 330 under its own weight, causing the other end of the pendulum 320 to strike the other end of the impact rod 231, thereby transmitting the impact force to the impact rod 231.

[0050] The impact assembly 300 also includes a semi-circular disk 340 and a release device 350. The semi-circular disk 340 is fixed to the upper part of the column 310, and the release device 350 is fixed on the semi-circular disk 340. The pendulum 320 is provided with a hanging plate 321, and the release device 350 is provided with a blocking part. The blocking part is used to block the hanging plate 321, so that the pendulum 320 is kept in a position corresponding to the fixed position of the release device 350.

[0051] Typically, the diameter of a thermal spray flame is 10 mm. In this embodiment, the substrate 100 adopts a disc-shaped structure with a diameter of 30 mm and a thickness of 3 mm. This size is significantly larger than the diameter of the spray flame, which facilitates the collection of individual flat particles within the diameter range of the spray flame as the substrate 100 passes through it. Simultaneously, the size of the substrate 100 also makes it convenient to place it into the scanning electron microscope sample chamber for observation.

[0052] Both the first guide member 210 and the second guide member 220 are provided with guide rail grooves, which are 3mm deep and 3.2mm wide. When fixing the first guide member 210 and the second guide member 220, it must be ensured that the base 100 can slide freely within the two guide rail grooves. That is, the first guide member 210 and the second guide member 220 are arranged in parallel and symmetrically.

[0053] The semi-circular disk 340 has an arc-shaped groove 341 for adjusting the fixed position of the release device 350. This means the position of the intelligent electromagnetic lock is adjustable, which in turn makes the starting position (i.e., starting height) of the pendulum 320 adjustable, thus adjusting the impact energy of the pendulum 320 after its downward swing. The adjustable impact energy of the pendulum 320 also adjusts the impact energy of the impact rod 231 striking the substrate 100. Different impact energies on the substrate 100 result in different speeds along the track, i.e., different speeds through the sprayed flame. Different speeds through the sprayed flame result in different amounts of collected and dispersed individual flat particles. Therefore, by adjusting the position of the intelligent electromagnetic lock, the amount of collected and dispersed individual flat particles on the substrate can be adjusted.

[0054] The device for collecting dispersed flat particles on the surface of the thermally sprayed substrate also includes a power supply 500 and a control switch 600. The control switch 600 is connected to the release device 350 and is used to control the operation of the release device 350. The power supply 500 is connected to the control switch 600 and the release device 350 and is used to provide the necessary electrical energy to the control switch 600 and the release device 350. The various electrical devices are connected by wires to transmit electrical energy or control signals. The release device 350 is an intelligent electromagnetic lock and the blocking part is a locking tongue.

[0055] In this embodiment, a pendulum mounting hole is provided at the connection between the pendulum 320 and the pendulum shaft 330. The pendulum mounting hole is clearance-fitted with the pendulum shaft 330. The pendulum mounting hole can be a 10mm diameter hole, and the distance from the pendulum mounting hole to the pendulum head can be 1m. The mounting plate 321 is made of 45# steel and is fixed to the pendulum 320 with M5 screws. The pendulum shaft 330 is also made of 45# steel, with a maximum diameter of 20mm and threaded ends at both ends. The threads at both ends are M8 and M5 respectively. One end of the M8 shaft is fastened to the column with a washer and nut. The diameter of the mounting hole for the pendulum 320 is slightly smaller than the diameter of the pendulum mounting hole, such as 9.8mm, to form a clearance fit. The width of the mounting hole should also be slightly larger than the width of the pendulum 320 to allow the pendulum 320 to rotate freely around the pendulum shaft 330. Alternatively, the pendulum 320 and the pendulum shaft 330 can be connected by bearings, allowing the pendulum 320 to rotate freely around the pendulum shaft 330. Place a large washer at the threaded end of the pendulum shaft 330M5, tighten it with a nut, and use the washer to block the pendulum 320 to prevent the pendulum 320 from slipping off the pendulum shaft 330.

[0056] The column 310 can be made of 20mm thick 45 steel plate or rectangular steel tube. It has holes with diameters of 9mm and 6mm at the top. The 9mm hole is for mounting the pendulum shaft 330, and the 6mm hole is for mounting the semi-circular disc 340. The height of the column 310 is determined by the length of the pendulum 320, ensuring that when the pendulum head reaches its lowest point, the center of the head strikes one end of the impact rod 231. A column base plate is provided at the lower end of the column 310. The column is vertically welded to the column base plate, which can be made of 10mm thick 45 steel plate. The screw holes on the plate are 10mm in diameter, and it is fastened to the base plate 400 with washers and M8 screws.

[0057] The semicircular disc 340 can be machined from 5mm thick No. 45 steel plate. It has four M5 internal thread holes for fixing to the column 310 with washers and M5 screws. A 21mm diameter hole is formed in the semicircular disc 340 for the pendulum shaft 330 to pass through. The semicircular disc 340 also has two semicircular grooves 341 for adjusting the fixed position of the release device 350. These grooves are for installing the intelligent electromagnetic lock. The semicircular groove design facilitates adjustment of the intelligent electromagnetic lock's installation position. The radius and width of the semicircular grooves are determined according to the installation requirements of the electromagnetic lock purchased from the market. Intelligent electromagnetic locks, such as the 99-A22 intelligent cabinet electromagnetic lock (12V, 0.6A), are purchased from the market and fixed to the semicircular disc with bolts and washers. The power supply is provided according to the requirements of the intelligent electromagnetic lock and is purchased from the market. The switch is a standard push-button switch.

[0058] like Figure 1 As shown, an opening slot 410 is provided on the base plate 400 along the movement path of the impact rod 231. The opening slot 410 is located below the movement path of the impact rod 231, and the opening end of the opening slot 410 is located on the side away from the impact rod sleeve 232.

[0059] In this embodiment, the base plate 400 can be made of 10mm thick No. 45 steel plate, and has threaded holes for installing the first guide member 210, the second guide member 220, the impact rod sleeve 232, and the column 310, etc., to facilitate the installation and disassembly of these components. The single flat particle collection device dispersed on the surface of the thermal sprayed substrate is simple to manufacture and easy to assemble. The position design of the threaded holes for fixing the first guide member 210 and the second guide member 220 must ensure that the first guide member 210 and the second guide member 220, i.e., the left and right guide rails, are symmetrically distributed on both sides of the extension line of the axis of the impact rod 231, and that after the impact assembly is installed, the middle front of the pendulum 320 hammer head hits one end of the impact rod 231 when the hammer head moves to the lowest point. The dimensions of the first guide member 210, the second guide member 220, and the impact rod sleeve 232 must also be designed to ensure that the distance from the axis of the impact rod 231 to the base plate is approximately equal to the distance from the base plate at half the thickness of the substrate.

[0060] The invention also discloses a method for collecting single flat particles dispersed on the surface of a thermally sprayed substrate using the aforementioned thermally sprayed substrate surface dispersed single flat particle collection device, characterized in that the method includes:

[0061] Push the substrate 100 to the right, i.e., the first position, and place the spray gun directly above the moving path of the substrate 100. Adjust the distance between the spray gun and the moving path of the substrate 100 according to the spraying process requirements, and at the same time make the spray gun perpendicular to the plane where the substrate 100 is located.

[0062] Adjust the installation position of the release device 350 as needed, and hang the pendulum 320 at the corresponding installation position of the release device 350 through the hanging plate 321;

[0063] Adjust the process parameters according to the spraying process, and start spraying by ignition;

[0064] Pressing the control switch 600 powers on the device, which immediately triggers the release device 350. The blocking part of the release device 350 retracts into the release device 350, the pendulum 320 disengages, the pendulum 320 swings downward, and the pendulum 320 strikes the impact rod 231. The impact rod 231 strikes the base 100, and the base 100 quickly passes through the sprayed flame along the first guide member 210 and the second guide member 220, thereby collecting and dispersing individual flat particles.

[0065] The process parameters include powder feeding rate and gas feeding rate.

[0066] The thermal spraying substrate surface dispersion single flat particle collection device of the present invention can adjust the starting position of the pendulum according to experimental requirements to generate impact forces of different magnitudes, so that the moving speed of the substrate is different, thereby obtaining the single flat particles required for the experiment. Figures 4 to 7 The distance between the spray gun and the substrate is 180mm. By adjusting the position of the electromagnetic lock, the starting position of the pendulum is changed. The images of the dispersed single flat particles collected are shown when the pendulum starts at an upward 45-degree angle, and when the pendulum starts at a horizontal position.

[0067] like Figure 1As shown, before spraying, push the substrate 100 to the position indicated by the dotted line, adjust the distance between the spray gun nozzle and the substrate 100 to the required distance, and simultaneously make the spray gun perpendicular to the base plate 400. Press the control switch 600 to power on, which immediately triggers the intelligent electromagnetic lock to unlock (lock head retracts), the pendulum 320 disengages, the pendulum 320 swings down, impacting the impact rod 231, and then impacting the substrate 100. The substrate 100 moves rapidly along the track, collecting individual flat particles. This allows the control switch 600 to be installed away from the spraying location, eliminating the hazards of the spraying environment to the operator. Pressing the control switch 600 completes particle collection. Furthermore, the device of this invention is simple to manufacture; all parts can be made through simple machining. Assembly is convenient, with only one connection requiring electric welding, and the rest requiring only screws and bolts.
