Abstract:
     The invention relates to magnesium and its alloy surface chemical copper plating method. It combines film coating with chemical copper plating to do composite protection. The film coating is after de-oiling, acid and alkaline cleaning. The film coating agent includes organic silicon heat resistant paint, organic titanium heat resistant paint WT61-1 and WT61-2, water glass base paint JN-801 silicate inorganic coating, silicone resin SF-7406 three proofing varnish, silane coupling agent KH550. After film coating it is processed sensitization, activation, and chemical copper plating. The formed chemical copper plating layer is uniform and has the appearance of metallic copper. The coating film has good ware, acid, and alkaline resistance. The cost and use level of copper sulfate are much less than chemical nickel plating. Thus the cost of invention is low; and its operation is simple; and suitable for industrialization production.
