FIELD: physics; chemistry.
SUBSTANCE: invention relates to production of permanent magnets based on Nd-Fe-B alloys. Proposed method comprises pressing workpieces, their machining, application of 10–15 mcm-thick aluminum layer with cold gas-dynamic sputtering and heat treatment in melt of salts with further cooling.
EFFECT: higher corrosion resistance of permanent magnets Nd-Fe-B.
