Abstract
The surface of Sm2Fe17N x fine powder was stabilized by coating with zinc metal produced by the photodecomposition of diethylzinc (Zn(C2H5)2). The remanence (B r) and coercivity (H cj) values of the resulting Zn/Sm2Fe17N x powder were changed little by zinc coating, and remained at high levels even after heat treatment at 423 K, since the oxidation-resistance was improved by the zinc coating. Epoxy resin bonded magnets prepared using the Zn/Sm2Fe17N x powder had a maximum energy product ( BH m a x ) value of 176 kJ·m-3, which did not change greatly after exposure to air. The irreversible flux loss of the bonded Zn/Sm2Fe17N x magnet was smaller than that of the uncoated Sm2Fe17N x magnet.Keywords
