In order to improve the performance of zinc coating under different conditions, tribological and neutral salt spray tests were conducted for the zinc coating dipped with sealant. The results showed that the treatment of dipping sealant after cyanide zinc plating could cover the micropores on the coating surface, and the corrosion resistance and color stability of coating were improved. Meanwhile, the friction force and friction coefficient of coating were reduced, and the service life was extended.%为进一步提高镀锌层在不同环境下的使用性能,通过摩擦磨损试验、中性盐雾试验,发现镀锌零件在氰化镀锌后增加浸涂封闭剂工序,能有效封闭镀层表面的微孔,提高零件的抗腐蚀能力；同时能降低镀层表面的摩擦系数和摩擦力,从而抑制磨损,能有效提高镀锌层的耐磨、耐蚀性能及产品的抗变色性能,显著延长零件的使用寿命.
