热喷涂技术被广泛用于机械零件磨损表面的修复。由于修复层具有较高的硬度,普通的机械加工方法加工困难,生产效率较低,刀具磨损严重,采用电解磨削加工方法对Ni-Cr-B-Si自熔性合金粉末修复的机械零件表面进行了加工,通过试验得出了电解液的配比及电解磨削规范。 Thermal spraying technology is widely used to repair the worn surface of mechanical parts. Due to the high hardness of the repaired layer, the common mechanical processing method is difficult to process, the production efficiency is low and the tool wear is serious. The surface of the mechanical parts repaired by Ni-Cr-B-Si self-fluxing alloy powder by electrolytic grinding method Processed, obtained through the test electrolyte ratio and electrolytic grinding specifications.
