Abstract
A closely adherent metal coating having a uniform thickness and substantially free from pinholes is formed on the porous surface of a bonded magnet to improve its oxidation and corrosion resistance without lowering its magnetic properties. The coating is formed by electroplating from an aqueous solution not containing chlorine, and having a pH of 5 or above. More particularly, the solution contains mainly nickel sulfate, an electrolyte in the form of an organic acid salt not containing chlorine, and a basic electrolyte not containing chlorine, and forms a nickel coating on the magnet surface.
