Role of sodium hypophosphite on morphology and corrosion resistance of Ni-P coated Nd-Fe-B

Uniform and dense electroless nickel (EN) was recognized as a promising protective coating for Nd-Fe-B magnets. However, large potential difference between intergranular phase and main phase of Nd-Fe-B made the deposition of EN coating uncontrollable. Sodium hypophosphite was use...
