电镀工艺主要是改善钢件表面性能 ,将它与热处理搭配起来就成了电镀热处理。将电镀后的零件加热到 5 5 0℃左右 ,然后通入氮气再水冷 ,通过这种电镀热处理 ,使镀层自身硬化 ,更加牢固 ,特别是在热处理温度下水冷 ,使镀层表面产生热应力 ,这对防止镀层脆性极为有利。把电镀 +热 Electroplating process is mainly to improve the surface properties of steel, heat treatment and it will become a combination of heat treatment. After plating the parts heated to about 5 5 0 ℃, and then pass into the nitrogen and then cooled by this plating heat treatment, the coating itself hardens, more solid, especially in the heat treatment temperature water cooling, so that the coating surface thermal stress, which To prevent brittleness is extremely favorable. Plating + hot
