摘要/Abstract

摘要： 以粉末冶金法制备了2∶17型Sm(Cobal Fe0.1 CuxZr0.033)7.4 (x=0.06,0.08,0.10)永磁体,研究了Cu含量对Sm(Cobal Fe0.1CuxZr0.033)7.4永磁合金的退磁曲线、磁能积、矫顽力、矫顽力温度系数等的影响.结果发现,Cu含量超过0.08以后会导致磁体的退磁曲线方形度降低,并进而导致磁体的磁能积降低;同时发现提高Cu含量,有利于提高2∶17型Sm(Cobal Fe0.1CuxZr0.033)74永磁体的室温及高温500℃的矫顽力,但高Cu含量也会导致矫顽力温度系数增大,使矫顽力在高温下衰减较快,这表明2∶17型SmCo永磁体的矫顽力与Cu元素的微化学成分分布密切相关.
