本文报道了金-氟化石墨自润滑复合镀层的电沉积工艺和影响复合镀层中氟化石墨含量的主要因素,并成功地研究出“HA-2”共沉积促进剂。 金-氟化石墨复合镀层的自润滑的程度,决定于复合镀层中氟化石墨的含量,可根据需要控制溶液中“HA-2”共沉积促进剂含量和pH值,来调节氟化石墨的含量,满足不同润滑要求。 金-氟化石墨自润滑复合镀层,在高低温使用环境条件下均具有优良的自润滑性能、电性能和可焊性能,并且不产生挥发物和污染物,是接插件、减磨器件比较理想的自润滑镀层。
In this paper, the electrodepositing process of gold-graphite fluoride self-lubricating composite coating and the main factors that affect the content of fluorinated graphite in the composite coating are reported. The “HA-2” co-deposition promoter has been successfully developed. The degree of self-lubrication of the gold-graphite fluoride composite coating depends on the content of fluorinated graphite in the composite coating. The content of the “HA-2” co-deposition promoter and the pH value in the solution can be controlled as needed to adjust the fluorinated graphite Content, to meet different lubrication requirements. Gold-fluorinated graphite self-lubricating composite coating has excellent self-lubricating property, electrical property and solderability under high and low temperature environment of use, and does not generate volatiles and pollutants. It is ideal for connectors and antifriction devices Self-lubricating coating.
