ELECTRODEPOSITION OF HARD MAGNETIC COATINGS

摘要

An aqueous electrolytic plating solution and a method of using the same for depositing a cobalt/nickel/phosphorus alloy on an electrically conductive substrate are provided. The aqueous electrolytic plating solution comprises: a) a source of nickel ions; b) a source of cobalt ions; c) a source of phosphite ions; d) an amino acid; and e) optionally, boric acid. The deposited cobalt/nickel/phosphorus alloy exhibits high coercivity and high remanence.
