Description

Technical Field

[0001] The present invention relates to the technical field of corrosion testing, and particularly to a corrosion testing device for cermet materials. Background Art

[0002] Cermet is a composite material composed of metal and ceramic, combining the toughness and electrical conductivity of metal with the high hardness, high temperature resistance and corrosion resistance of ceramic, and is widely used in industries, aerospace, electronics and other fields.

[0003] Referring to the Chinese invention patent with the publication number: CN 117169103 B and the name: A corrosion testing device for ultra-high temperature ceramic materials, the invention includes a testing platform, a material conveying mechanism, a testing rack, a testing mechanism and an auxiliary testing component. A detection through-hole is opened on the testing platform. The material conveying mechanism is arranged on the testing platform. The material conveying mechanism includes a conveying component and two mirror-image arranged loading components for conveying the ultra-high temperature ceramic materials. The testing rack is arranged on the testing platform. The testing mechanism is arranged on the testing rack. The testing mechanism includes a testing cover with a position adjustment function. A corrosion testing head is arranged in the testing cover. A corrosion testing component is arranged on the corrosion testing head. The auxiliary testing component is arranged on the testing rack. Through the above technical solutions, the invention solves the problems that in the prior art, when a fatigue testing machine conducts corrosion testing on ultra-high temperature ceramic materials, not only the preparatory work is cumbersome, but also the testing cycle is long.

[0004] However, in the actual use process, the above and similar technical solutions still have some problems:

[0005] 1. In the process of using the testing cover to encapsulate the surface of the ceramic plate for performance testing, all test steps including grinding and corrosion resistance testing are completed inside the closed testing cover. This process requires the testing cover to remain airtight throughout the testing cycle. However, due to the long time-consuming corrosion resistance testing, the configuration of existing single devices limits the ability to process multiple ceramic plate samples simultaneously, reducing the detection efficiency;

[0006] 2. The debris generated during the grinding operation is confined to the internal space of the testing cover, lacking an effective collection mechanism. This not only increases the difficulty of subsequent cleaning, but also the grinding area and the corrosion detection area overlap in space. This design deficiency may cause the protective coating on the surface of the ceramic plate to be removed or damaged during the grinding process, thereby having an adverse impact on the subsequent corrosion detection results and reducing the accuracy and reliability of the test results;

[0007] 3. When removing the test cover after the test, due to limitations in design or operation, it is difficult to completely extract the liquid used in the corrosion test, resulting in residual corrosive liquid inside the test cover. This not only increases the operational complexity but also may contaminate the ceramic plate and the test environment. At the same time, the residual corrosive liquid poses a safety hazard when removing the ceramic plate, making it inconvenient to perform subsequent processing or analysis of the sample safely and efficiently.

[0023] Compared with the prior art, the present invention provides a metal ceramic material corrosion test device, which has the following beneficial effects:

[0024] 1. For this metal ceramic material corrosion test device, place the ceramic plate between the slider and the pressing plate. Press down the slider to make the lead screw snap into between a pair of first clamping blocks. The first motor drives the lead screw to rotate, thereby driving the first clamping blocks and the slider to move, making the slider approach the hardness detector. The sliding arm drives the support rod to abut against the surface of the pressing plate. When the pressing plate slides down, the first tooth groove pushes the first tooth block to move. The first spring pushes the first tooth block to engage with the first tooth groove, thereby restricting its upward reset when the pressing plate slides down, so as to ensure that the ceramic plate is firmly fixed. Start the second electric push rod to push the probe of the hardness detector to abut against the surface of the ceramic plate, so as to facilitate measuring the hardness of the ceramic plate. The ceramic plate is convenient to fix and the operation is simple.

[0025] 2. For this metal ceramic material corrosion test device, start the third electric push rod to push the fixed shell to move down. The bottom ends of the fixed frame and the grinding belt will abut against the surface of the ceramic plate, thus forming a closed space. The grinding belt grinds the surface of the ceramic plate to detect the wear resistance of the ceramic plate. During the grinding process, the debris ground off flies out along the movement direction of the grinding belt, so that the debris enters the interior of the collection bottle, which is convenient for later removing the collection bottle to collect and observe the debris.

[0026] 3. In the metal ceramic material corrosion testing equipment, when the sliding arm moves downward, the injection tube is inserted into the one-way valve at the top of the gland, and the bottom of the gland contacts the surface of the ceramic plate. The corrosive liquid is injected into the interior of the sliding tube through the injection tube and the one-way valve by the liquid pump. The liquid will accumulate at the bottom of the piston, thereby pushing the piston to move upward. The seventh spring will be compressed and the injection tube will be pulled out, thereby retaining the corrosive liquid at the bottom of the piston. The corrosive liquid contacts the surface of the ceramic plate, thereby performing corrosion detection. The third motor is started, and the cotton belt moves through the through hole to pull the slider for injecting the corrosive liquid to move, and the slider moves to one side of the slide rod, thereby It is convenient to wait for the corrosive liquid to react, and other ceramic plates can still be operated during the waiting process. After the reaction is completed, press the second push block to release the limit on the pressure cover, the pressure cover will be separated from the ceramic plate, the piston slides downward, the corrosive liquid is released, and the cotton belt absorbs it to avoid spilling. The cotton belt is driven to move, so that the cotton belt can be rubbed against the surface of the ceramic plate, thereby wiping the ceramic plate, which is convenient for cleaning the corrosive liquid. At the same time, when it is necessary to take out the middle slider, the cotton belt can be cut with scissors, the slider can be pulled out, and the cut cotton belt can be bonded by Velcro, which is convenient for automatic wiping of other ceramic plates, and has high flexibility.

The second tooth block 732 abuts against the pressure cover 71 through the second tooth groove 735, so as to facilitate the limitation of the pressure cover 71 and prevent the pressure cover 71 from separating from the ceramic plate 8.

[0052] Working principle: Place the ceramic plate 8 between the slider 21 and the pressure plate 22. A groove can be provided on the slider 21 to initially limit the ceramic plate 8 and prevent it from detaching. Align the first clamping block 351 at the bottom of the slider 21 with the screw rod 32, press the slider 21 downward, and insert the screw rod 32 between the pair of first clamping blocks 351. Under the action of the second spring 352, the first clamping block 351 and the screw rod 32 are lifted. The pair of first clamping blocks 351 are threadedly connected with the screw rod 32, and the first motor 31 is started. The first motor 31 drives the screw rod 32 to rotate, thereby driving the first clamping block 351 and the slider 21 to move, so that the slider 21 is close to the hardness detector 53. When the slider 21 is close to the hardness detector 53, the first clamping block 351 is separated from the screw rod 32, and the second motor 33 is started. The second motor 33 drives the push wheel 34 to rotate, and the protruding end of the push wheel 34 will contact the side end of the slider 21, thereby pushing the slider 21 to approach the hardness detector 53. The end of the slider 21 contacts the bracket 1, and the bracket 1 The hardness detector 53 is located directly above the slider 21. The first electric push rod 52 is started and contracted, thereby pulling the slide arm 51 downward. The slide arm 51 drives the support rod 55 to contact the surface of the pressure plate 22. The support rod 55 pushes the pressure plate 22 to slide downward. The pressure plate 22 contacts the surface of the ceramic plate 8, thereby limiting the ceramic plate 8. When the pressure plate 22 slides downward, the first tooth groove 235 pushes the first tooth block 234 to move, and the first spring 233 pushes the first tooth block 234 to move. The first tooth block 234 is engaged with the first tooth groove 235, so that when the pressing plate 22 slides downward, it is restricted from resetting upward, thereby ensuring that the ceramic plate 8 is firmly fixed, and the first push block 231 is pressed to push the first tooth block 234 away from the pressing plate 22 through the inclined groove 232, thereby releasing the limit on the pressing plate 22, so as to facilitate clamping the ceramic plate 8 again, and start the second electric push rod 54, so as to push the probe of the hardness detector 53 to contact the surface of the ceramic plate 8, so as to facilitate the measurement of the hardness of the ceramic plate 8;

[0053] When the slider 21 is located below the hardness detector 53, since the pressing plate 22 is stepped, the cotton tape 43 will be inserted between the pressing plate 22 and the ceramic plate 8. There are through holes on the cotton tape 43, and the through holes on the cotton tape 43 are aligned with the gland 71. Start the third electric push rod 63, and the third electric push rod 63 extends, thereby pushing the fixed shell 62 downward. The bottom end of the fixed shell 62 is inserted into the inside of the fixed frame 61, pushing the fixed frame 61 downward, and the fourth spring 67 is compressed. The bottom ends of the fixed frame 61 and the grinding belt 64 will contact the surface of the ceramic plate 8, thereby forming a closed space. Start the fourth motor 66, and the fourth motor 66 will drive the rotating wheel 65 to rotate, thereby driving the grinding belt 64 to rotate. The grinding belt 64 grinds the surface of the ceramic plate 8, thereby detecting the wear resistance of the ceramic plate 8. During the grinding process, the debris ground off flies out along the movement direction of the grinding belt 64, so that the debris enters the inside of the collection bottle 69, which is convenient for later removing the collection bottle 69 to collect and observe the debris. A filter screen 68 is installed at one end of the fixed frame 61 to facilitate balancing the pressure inside the fixed frame 61;

[0054] When the slide arm 51 moves downward, the injection pipe 77 is inserted into the one-way valve 72 at the top of the gland 71, thereby pushing the gland 71 to slide downward, the sixth spring 734 is compressed, the bottom end of the gland 71 contacts the surface of the ceramic plate 8, and the fifth spring 733 pushes the second tooth block 732 to engage with the second tooth groove 735, thereby limiting the gland 71 from resetting upward. The bottom end of the gland 71 is made of rubber material to achieve sealing. In the initial state, the seventh spring 75 pushes the piston 74 to contact the surface of the ceramic plate 8, and the corrosive liquid is injected unidirectionally through the injection pipe 77 and the one-way valve 72 through the liquid pump. When the piston 74 is pushed upward, the seventh spring 75 is compressed, and the injection tube 77 is pulled out, so that the corrosive liquid is retained at the bottom end of the piston 74. The corrosive liquid contacts the surface of the ceramic plate 8, so that corrosion detection is performed. The third motor 423 is started, and the third motor 423 rotates. Under the action of the gear 422, a pair of pressure rollers 421 are driven to rotate, thereby driving the cotton belt 43 to move in the direction of the pressure roller 421, so that the cotton belt 43 is released from the storage box 41, and the cotton belt 43 is pulled through the movement of the through hole. The slide block 21 for injecting the etching liquid moves, so that the slide block 21 moves to one side of the slide bar 45. When the push wheel 34 pushes the slide block 21, a pair of second clamping blocks 461 at the bottom of the slide block 21 clamps the slide bar 45, and the third spring 462 restricts its separation. The slide block 21 moves to one side of the slide bar 45, so as to wait for the etching liquid to react. During the waiting process, other ceramic plates 8 can still be operated. After the reaction is completed, the second push block 731 is pressed, so as to push the second tooth block 732 to separate from the second tooth groove 735, thereby releasing the limit on the pressure cover 71, and the sixth spring 734 The seventh spring 75 is extended, thereby pushing the pressure cover 71 to rise, and the pressure cover 71 will be separated from the ceramic plate 8. The seventh spring 75 is extended, and the piston 74 slides downward, the corrosive liquid is released, and the cotton tape 43 absorbs it to prevent it from spilling. The cotton tape 43 is driven to move, so that the cotton tape 43 can be rubbed against the surface of the ceramic plate 8, thereby wiping the ceramic plate 8, which is convenient for cleaning the corrosive liquid. At the same time, when it is necessary to take out the middle slider 21, the cotton tape 43 can be cut with scissors, and the slider 21 can be pulled out. The cut cotton tape 43 can be bonded by Velcro 44, which is convenient for automatic wiping of other ceramic plates 8.
