Abstract
The invention provides a sample thickness control device and method for electrolytic polishing, and the device comprises a top plate which is provided with clamping grooves which are uniformly distributed, and the clamping grooves can be used for vertically placing electrodes; scale lines are arranged between the clamping grooves, and the distance between the electrodes can be accurately adjusted by adjusting the positions of the electrodes in the clamping grooves. And the clamping groove and the scale marks are arranged on the acrylic plate on the top plate. And the electrode can vertically fall into the polishing solution from the clamping groove. The top plate is provided with a buckle capable of fixing the acrylic plate. According to the device provided by the invention, the relative position of the cathode and the sample can be accurately adjusted, so that the uniformity of the electrolytic polishing process is ensured, and the problem of non-uniform polishing caused by non-uniform distance is avoided; according to the invention, comprehensive control on the electrolytic polishing process, including power supply voltage, polishing time and sample thickness removal amount, can be realized, so that the surface of the final sheet sample is smoother and more uniform, and the thickness is accurate and controllable.
