摘要
本文以氮气雾化2Mo81Ni17Fe合金粉末为原料,采用粉末冶金方法制备了2Mo81Ni17Fe磁粉芯,测试了磁粉芯的磁导率。主要讨论了磁粉芯磁导率的影响因素。结果表明,磁粉芯的磁导率随着绝缘剂添加量的增加而减少,随着压制压力以及热处理温度的提高而上升。
The magnetic powder core was manufactured using 2Mo81Ni17Fe atomized powder and. it＇s permeability was measured and influencing factors of permeability were analysed. The results show that the permeability is decreased with the increase of content of added insulater and increased with the increase of forming pressure and annealing temperature.
