摘要
本文介绍了Sm_2(Co.Cu.Fe.Zr)_(17)稀土永磁合金中钐含量对合金磁性能的影响,并研究了液相烧结工艺中不同的液相合金添加量对合金性能的作用。研究结果表明,添加液相合金后容易获得较好而稳定的磁性能。与常规的2:17稀土永磁合金相比,合金的矫顽力iHc和最大磁能积(BH)_(max)分别提高48kA/m和16kJ/m^3左右。采用液相烧结工艺还可以实现人为调节合金成分,因此提高产品的合培率,对批量生产磁体具有很大的经济价值。
This paper has introduced the effects of Sm Content on the magnetic properties of Sm_2(Co, Cu, Fe, Zr)_(17) rare earth permanent magnets. The influences of various liquid alloy additions during liquid phase sintering process on the properties of alloy have also been studied. The Results have shown that it is easy to have botter and stailizing magnetic properties by adding liquid phase alloy. Intrinsic coercive force, iHc and energy product. (BH)_(max) can be increased to about 48kA/m and 16kJ/m^3 respectively when compared with those of conventional 2: 17 rare earth alloy. Alloying composition can be manually tailored by liquid phase sintering, and thus rate of qualified products increases and commercial production of this magnets has great economic effect.
