摘要
全面介绍了采用注射成形技术制备烧结NdFeB永磁体的工艺过程;总结了粘结剂、磁场取向及成形、脱脂和烧结工艺对最终产品的影响;比较了注射成形和传统粉末冶金压制成形制备的NdFeB磁体的性能;在分析现状的基础上,指出了现阶段存在的问题。
The process of making sintered NdFeB permanent magnets by powder injection molding is reviewed comprehensively in this paper. The influnces of binder,magnetic alignment,molding,debinding and sintering on the products are summarized,and a comparison is made between performance of PIM sintered NdFeB to that made by traditional molding. Finally existing problems are pointed out.
