Fe-Nd-B magnets were prepared by the powder metallurgical process. The magnets were coated with TiN or ZrN by using the reactive triode ion plating technique in order to improve the corrosion resistance. The special purpose of the present work was to combine the coating process with the heat treatment of the magnets. Magnetic and corrosion properties of the coated magnets are reported in the present study.
