Paper Title:
Research on the Surface Treatment of Magnetic Powder in Bonded Nd8Fe80B6Co6 Alloy
  Abstract

Nd, Ce and Pr in ER-magnets are very active and easy react with oxygen and other oxidizing substance [1]. So this paper deals with the formation of some organic films on the Nd8Fe80B6Co6 magnetic powders. Then the belt of the alloy was made in a melt-spun furnace and then heat-treated at certain temperature. After that the magnetic powders were prepared by special crashing techniques. Epoxy resin and titanate were chosen as coat materials. The test showed that the epoxy-titanate coating material has the lowest weight increase in the exposure of oxidation atmosphere. Effects of the coat materials on the properties of bonded alloy were also investigated. The magnetic properties of the alloy with epoxy-titanate coating material were similar to one without coat.
