电刷镀的基本原理与电镀(槽镀)相同,都属于电化学结晶过程,刷镀是在通电状态下蘸镀液的阳极与被镀工件表面做相对接触运动下进行化学反应而施镀的,由于刷镀镀液浓度高和电流密度大,所以镀层沉积速度快,并且具有接合力强、硬度高、耐摩擦性能和耐高温性能好的特点。因此电刷镀工艺适合发动机轴类零件的修复。 The basic principle of brush plating and plating (groove plating) are the same, are electrochemical crystallization process, brush plating is energized state dipped in the bath of the anode and the surface to be plated to make contact with the movement of the chemical reaction and plating , Due to the high concentration of brush plating bath and current density, so the coating deposition speed, and has strong bonding, high hardness, high friction and high temperature performance. Therefore brush plating process for the repair of engine shaft parts.
