The technological process of electroplating Ni-W alloy on ABS plastics mainly includes: de-stress, deoiling, pickling, coarsening, neutralization, primary reduction, pickling, sensitization, activation, secondary reduction, electroless copper plating, weak etching, thickening copper acid plating, Ni-W alloy plating and drying. The electroplating bath of Ni-W alloy is composed of nickel sulfate hexahydrate, sodium tungstate dihydrate, citric acid and ammonia (pH regulator). Under the condition that the total mass concentration of nickel sulfate hexahydrate and sodium tungstate dihydrate is 210g/L and the amount of citric acid is equal to the total amount of nickel sulfate and sodium tungstate dihydrate, the effects of mass concentration ratio of nickel sulfate hexahydrate to sodium tungstate dihydrate, bath temperature, pH and current density on the microhardness, wear resistance, adhesion and surface morphology of the coating were discussed by orthogonal test. The optimum process conditions are as follows: nickel sulfate hexahydrate 60g/L, sodium tungstate dihydrate 150g/L, citric acid 130g/L, bath temperature 65 °C, pH5, current density 20A/dm2, plating time 45min, nickel plate as anode, magnetic stirring. The surface of the coating obtained by this process is fine, smooth and glossy, with high microhardness, good adhesion and excellent wear resistance.
ABS plastic is a terpolymer of acrylonitrile, butadiene and styrene. It is one of the most widely used engineering plastics. It is widely used in machinery, automobile, electrical appliances, communication equipment, chemical industry, construction and other fields.
Electroplating Ni-W alloy on the surface of ABS plastic can combine the light weight, non-toxic, impact resistance and easy processing of plastic with the properties of high hardness, high wear resistance and strong corrosion resistance of Ni-W alloy coating, and further broaden its application range.
