Cailiao baohu 2001,34(2),21∽ 22(Ch). The technological process and parameters for amorphous Ni-P alloy plating of Nd-Fe-B permanent magnetic materials were described. The factors affecting the quality of coating including current density, temperature, pH value and phosphorous acid content were discussed. It was shown that the coating was good in adhesion and corrosion resistance.
