摘　　要：本文研究了手表柄头滚镀金加工技术,另件经除油、浸酸后,先滚镀光亮镍,再滚镀金钴合金,采用柠檬酸盐镀液,温度为30～50℃,Dk0.5～1.5A/dm^2。本文对温度、pH值及电流密度对镀层厚度、硬度、光洁度及色泽的影响均作了研究。最后所得的制品,其硬度为Hv 160、厚度5μm、表面光洁度▽ 9级以上,满足了生产上的技术要求。The barrel gold plating technique for the crown of wrist watch is studied. After degreasing and pickling, the parts are first barrel plated with bright nickel, followed by gold cobalt alloy plating. Citrate bath is used to barrel plate gold cobalt alloy at temperature 30-50℃ and D_k=0.5-1.5A/dm^2. The effects of temperature, pH value and current density on thickness, hardness, fineness and color shade of the coating are also discussed. The final product obtained with hardness of Hvl60, thickness 5μm and surface fineness over ▽ 9 can meet the technical requirements of practical production.
