Description

TECHNICAL FIELD

[0001] The utility model relates to the microcosmic characterization technical field of metal material, and specifically relates to an anode tool for optimizing electrolysis effect. BACKGROUND

[0002] Electron backscatter diffraction (EBSD) is a crystal micro-area orientation and crystal structure analysis technique widely used in scanning electron microscopes (SEM). It obtains the crystallographic information of the crystal sample, such as the interplanar spacing and interplanar angle of the crystal sample, by analyzing the Kikuchi pattern obtained from the high-energy electron diffraction of the crystal sample surface, and further determines the structure and orientation of the crystal sample. Although EBSD can be applied to various crystal materials, including non-metallic crystals such as minerals, in practical applications, metal samples have become one of the main objects of EBSD analysis due to their wide application and technical needs. In order to obtain high-quality EBSD data, the surface of the metal sample must have good flatness and smoothness, which is usually achieved through electrolytic polishing. During electrolytic polishing, the metal sample is placed as an anode in an electrolytic cell and is selectively dissolved by applying a direct current to it to remove its surface defects and improve its surface quality.

[0003] However, the existing electrolytic polishing method mainly uses a wire clamp to directly clamp the metal sample for electrolytic polishing. This method has the following disadvantages: First, since the device used is relatively simple, manual control of the position of the metal sample is often required. Manual control can easily cause the depth of the metal sample in the electrolyte to change, resulting in not only unstable electrolysis process and affecting the electrolysis effect, but also the metal sample easily falling off the wire clamp. Second, when processing metal samples of different shapes and sizes, the applicability of the wire clamp is poor, and it cannot ensure that each metal sample can be uniformly and effectively electrolytically polished, thereby affecting the final EBSD analysis results.

[0004] Therefore, it is necessary to invent an anode tool for optimizing electrolysis effect to solve the above problems. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0018] The vibration motor 5 is electrically connected with the timer;

[0019] The controller is electrically connected with the temperature measuring rod 4, the vibration motor 5, the timer and the digital display panel 6 respectively.

[0020] The cover plate 15 cooperates with the anode fixing seat 1 to provide a stable platform for the sample to be electrolyzed 3 during the electrolytic polishing process, the conductive clamp 2 is used to firmly clamp the sample to be electrolyzed 3, so that the sample to be electrolyzed 3 can maintain a stable position during the electrolytic polishing process, avoiding the risk of the sample to be electrolyzed 3 falling off from the conductive clamp 2, and solving the instability problem caused by manual control in the existing electrolytic polishing mode.

[0021] The longitudinal section of the anode fixing seat 1 is T-shaped.

[0022] The structure design not only increases the overall stability of the anode tool, but also provides more space for installing other components, such as the digital display panel 6 and the vibration motor 5.

[0023] The clamping end of the conductive clamp 2 is U-shaped, and the clamping end of the conductive clamp 2 is threadedly connected with a ceramic screw 7, the sample to be electrolyzed 3 is located on the inner side of the conductive clamp 2, and the end of the ceramic screw 7 abuts against the side wall of the sample to be electrolyzed 3.

[0024] The structure design of the U-shaped clamping end of the conductive clamp 2 cooperating with the ceramic screw 7 can adapt to samples to be electrolyzed 3 of different sizes and shapes, by providing a certain elastic space, allowing the clamping of samples to be electrolyzed 3 of different thicknesses without complex adjustment, overcoming the poor applicability problem of traditional clamps, and by using the ceramic screw 7, sufficient pressure can be applied to fix the sample to be electrolyzed 3 without damaging the surface of the sample to be electrolyzed 3, enhancing the stability of clamping, and the selection of ceramic material avoids the problem of electrochemical corrosion caused by metal contact.

[0025] The anode mounting hole of the cover plate 15 is filled with buffer foam 14 between the outer side wall of the anode fixing seat 1.

[0026] The structure design of the buffer foam 14 plays a shock-absorbing role, prevents the falling of the to-be-electrolyzed sample 3 during electrolytic polishing, and further improves its stability.

[0027] Before electrolytic polishing, as shown in the accompanying drawings, an adjustable DC voltage stabilizing power supply 8, a first wire 9, a second wire 10, a beaker 11, an electrolyte 12, an inert cathode 13, and the present anode tooling are prepared. Figure 2

[0028] In use, the positive output end of the adjustable DC voltage stabilizing power supply 8 is connected to the upper end of the conductive clamp 2 through the first wire 9, and the negative output end of the adjustable DC voltage stabilizing power supply 8 is connected to the upper end of the inert cathode 13 through the second wire 10. Then the electrolyte 12 is poured into the beaker 11, ensuring that the height of the electrolyte 12 in the beaker 11 is higher than half the height of the beaker 11. The cover plate 15 is placed on the beaker 11, and the to-be-electrolyzed sample 3 is clamped by the conductive clamp 2 and the ceramic screw 7. The temperature probe 4 on the anode fixing seat 1 is started by the controller, and the timer is set by the controller. The inert cathode 13 is inserted into the beaker 11, ensuring that the lower part of the inert cathode 13 is immersed in the electrolyte 12. The anode fixing seat 1 is inserted into the beaker 11, ensuring that the clamping end of the conductive clamp 2 and the to-be-electrolyzed sample 3 are fully immersed in the electrolyte 12. At the same time, the buffer foam 14 is filled between the anode mounting hole of the cover plate 15 and the outer side wall of the anode fixing seat 1 to ensure stable installation. The adjustable DC voltage stabilizing power supply 8 is started, and its voltage value is adjusted to the required electrolysis voltage value. At the same time, the timer and the vibration motor 5 are started by the controller, and the electrolytic polishing of the to-be-electrolyzed sample 3 begins. When the electrolysis time reaches the set time, the vibration motor 5 automatically stops. The anode fixing seat 1 is removed, and the electrolytic polishing completed to-be-electrolyzed sample 3 is taken out. After rinsing with running water, the electrolytic polishing completed to-be-electrolyzed sample 3 is placed in anhydrous ethanol for ultrasonic cleaning, thereby completing the electrolytic polishing of the to-be-electrolyzed sample 3. The problems of unstable operation, easy falling of metal samples, and poor applicability of traditional clamps to metal samples of different shapes and sizes in the existing electrolytic polishing method are overcome.

[0029] ​The temperature measuring stick 4 can monitor the temperature of the electrolyte 12 in real time, and ensure that the electrolytic polishing process is carried out in the designed temperature range, which is crucial for optimizing the electrolytic polishing effect; the structure design of the timer combined with the vibration motor 5 can make the vibration motor 5 shake the conductive clamp 2 within the set time, so as to promote the electrolyte 12 to fully contact the surface of the sample 3 to be electrolyzed, and improve the uniformity and efficiency of the electrolytic polishing; the digital display panel 6 is electrically connected with the controller, and can display the time and temperature in the electrolytic polishing process in real time, so as to facilitate the staff to monitor the whole electrolytic polishing process, and through the automatic control, the instability caused by manual operation is reduced, and the quality and efficiency of the electrolytic polishing are improved.

[0030] The digital display panel 6 is a touch screen digital display panel, which is a prior art and will not be described in detail here.

[0031] In the implementation process, before the conductive clamp 2 clamps the sample 3 to be electrolyzed, the sample 3 to be electrolyzed is first polished and pretreated, and the sample 3 to be electrolyzed is processed into a small square piece with a length of 5 mm, a width of 5 mm and a thickness of 2 mm by using the electric spark cutting technology, and the surface to be characterized is coarsely ground by using sandpaper with different mesh numbers, so as to ensure that the surface to be characterized is flat enough, and the mesh numbers of the sandpaper are 400 mesh, 1000 mesh, 2000 mesh and 3000 mesh; then the sample 3 to be electrolyzed after coarse grinding is polished on a grinding and polishing machine by using a silicon dioxide suspension, the average particle size of the silicon dioxide is 50 nm, and the polishing time is 20 min; the surface of the sample 3 to be electrolyzed after polishing is flat, has mirror gloss and no scratches can be seen by naked eyes, and the sample 3 to be electrolyzed after polishing can be subjected to subsequent electrolytic polishing.
