Development of Methods to Improve Corrosion Resistance of Hard-Magnetic Sm2Fe17N3 Materials

Corrosion resistance of hard magnetic Sm 2 Fe 17 N 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 2...

Description
Summary:	Corrosion resistance of hard magnetic Sm 2 Fe 17 N 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 2 Fe 17 N 3 powder with organosilicon liquid GKZh 136-41 makes it possible to improve corrosion resistance by a factor of 2–3.
