The Study on Preparation and Apply of Ni-Co-P Alloy Coating

Abstract

The study on combinatorial additives and plating technics for preparation and apply Ni-Co-P alloy coating was carried out completely, and the Ni-Co-P alloy with functional, corrosion-resistance and ornamental multicomponents was found, the optimum technics of plating multicomponents alloy was been found. The coating made in optimum technics was good in corrosion-resistance and wear-resistance, and with a smooth, fine, shining surface. It was proved by determinations that the 8.2% phosphorus in the coating and the coating was amorphous crystal. It was found that the combination force between the substrate and coating was very good, the corrosion-resistance and abrasion-resistance of coating were much better than that of Ni-P alloy according to the examination, the Ni-Co-P alloy coating with special character which were good magnetic properties and finery in ornamentally also.
