Coercivity mechanism of sm co , fe , cu , zr z sintered magnets and its influencing factors 的矫顽力机制及其影响因素
The highest sintering temperature was 900 c , and the sintering lasted 70 seconds . the conventional sintered magnets were sintered at 1000 c for 1h 常规烧结的温度为1000 ,烧结时间为1h ,并分别在800和600各进行1h的回火。
The former will destroy the protection of hydrogen and result in oxidation of the magnetic powder , eventually decreasing the magnetic energy product . but the latter will decrease the alignment of sintered magnets 前者会失去氢的保护,导致磁粉氧化,磁能积下降;后者会影响烧结磁体的最终取向度。
