Process and Properties of Electroless Plating of Ni-P Alloy on Brass

The process for electroless plating of Ni-P alloy on brass has been investigated. The composition, structure, binding power and corrosion resistance of the plating are analysed. The results show that Ni-P plating of amorphous structure with more than 12 wt% phosphorus content can be obtained, which possesses strongly adhesive power to the substrate and excellent corrosion resistance.
