Abstract Pure silver and silver-graphite composite coatings were prepared by vacuum cyanide-free electroplating method. The results show that the plating current has great influence on the sulfur-resistant properties of the coa-ting, and the coating prepared at the current density of 0.4 A/dm2 has good sulfur-resistant properties. Compared with commercial silver plating, the pure silver and silver-graphite composite coating prepared by vacuum electroplating has significantly improved sulfur resistance. Vacuum electroplating can effectively improve the compactness of the coa-ting and thus improve the vulcanization resistance of the coating.
