technical field [0001] The invention relates to the technical field of electrolysis processing, in particular to an electrolysis cathode, a cathode processing method, an electrolysis system containing the cathode and a method for using the system. Background technique [0002] Studies have shown that surface micro-texture technology is an effective means to improve the tribological properties of the friction pair surface. At present, the surface fine texture has been successfully applied in engineering technology fields such as cylinder liners, sliding bearings and mechanical seals. Therefore, low-cost, high-efficiency, and high-precision surface texture processing technology has become a research hotspot in the field of manufacturing, and it is also a technical problem.

AI Technical Summary

Problems solved by technology

However, the micro-abrasive air jet processing technology is only suitable for processing hard and brittle materials, and at the same time causes serious environmental pollution.

3) The EDM method processes a large amount of micro-textures. The production of electrodes is a technical difficulty. A large number of micro-textures are processed, and the characteristics of EDM also determine that there must be heat-affected zones and microscopic cracks around the texture.

4) The electro-jet machining technology is used for the processing of massive arrays of micro-textures, and can accurately process various surface textures on planes and curved surfaces. However, this process belongs to single-point or single-row processing, and the processing efficiency is relatively low, and the processing The stray corrosion around the mass of micro-textures produced is relatively serious, which cannot meet the requirements of use.

If this method needs to process arc-shaped surfaces with different curvature radii, the fixture must be remade, which cannot realize small batches and diversified flexible production
