Development of Methods to Improve Corrosion Resistance of Hard-Magnetic Sm.sub.2Fe.sub.17N.sub.3 Materials

Corrosion resistance of hard magnetic Sm.sub.2Fe.sub.17N.sub.3 materials is studied. It is shown that addition of cobalt (up to 8 wt.%) makes it possible to improve corrosion resistance of these materials by 20-25% without reducing their magnetic properties. It is established that additional treatme...

Description
Summary:Corrosion resistance of hard magnetic Sm.sub.2Fe.sub.17N.sub.3 materials is studied. It is shown that addition of cobalt (up to 8 wt.%) makes it possible to improve corrosion resistance of these materials by 20-25% without reducing their magnetic properties. It is established that additional treatment of Sm.sub.2Fe.sub.17N.sub.3 powder with organosilicon liquid GKZh 136-41 makes it possible to improve corrosion resistance by a factor of 2-3.
