Abstract

The electroless plating technics of copper on plastic substrate was researched, and on this basis, the Ni-W-P alloy plating technics on aforementioned plastic substrate was researched. The optimum electroless plating technics, plating technics and bath were found. The coating made in optimum technics was excellent in corrosion-resistance, wear-resistance, oxidation-resistance, and with a smooth, fine, shining surface. It was proved that the 8.1% phosphorus in the coating and the coating was amorphous crystal by determinations, the combination force between the substrate and the coating was very good, the properties of coating to resist corrosion and abrasion were 4 times better than that of Ni-P alloy by the tests. The coating was finery in ornamentally also.
