coercive force

Study of saturation magnetization and coercive force of Ti(CN) base cermets;

Ti(CN)基金属陶瓷饱和磁化强度和矫顽磁力的研究

The factors that affect the coercive force of cemented carbides are analyzed theoretically.

从理论上分析了硬质合金矫顽磁力的影响因素,指出在高温工况和实际生产工况中,炉控片的矫顽磁力主要与最高烧结温度有关。

Using back scattered electrons, Co-% magnetism meter, coercive force meter and chemical analysis etc, the compositions, Co-% magnetism and coercive force of vacuum sintering cermets are studied.

用背散射电子像、钴磁仪、矫顽磁力计、化学分析等手段研究了真空烧结金属陶瓷合金的成分、晶格常数与其钴磁及矫顽磁力的关系。

The experimental regularity and the mechanism of coercitive force of me-tallic cobalt powders and WC-Co mixture powders used for WC-Co cemented carbides production have been explored,The results show that the specific Coer-citive force Hsc is practlcal physical measure which can show exactly the de-magnetization characteristic of cobalt,magnitude of which is related to struc-ture of cobalt.

结果表明，比矫顽磁力Ｈｓｃ是能确切表明Ｃｏ的退磁特性的实用物理量，其值与Ｃｏ结构类型有关；ＷＣ－Ｃｏ混合粉的Ｈｓｃ在Ｃｏ结构一致的条件下与其中Ｃｏ含量具有简单的正向对应关系，其值随Ｃｏ粒细化和Ｃｏ粉在混合料中分布均匀化而提高并归因于该混合物中相邻ｃＯ拉磁矩间的相互作用和颗粒间残余应力因研磨作用的增加。
