摘要:

利用化学镀方法首次成功地制备了Ｆｅ－ＴＭ－Ｂ（ＴＭ＝Ｓｎ，Ｗ，Ｍｏ－Ｗ）合金，采用ＶＳＭ研究了合金施镀态和热处理后的磁性。结果表明：随镀层中Ｆｅ含量的增加和热处理温度的降低，镀层饱和磁化强度出现增加趋势，在Ｂ含量分别为１４．９ａｔ％和９．３ａｔ％时，Ｆｅ－Ｓｎ－Ｂ和Ｆｅ－Ｗ－Ｂ镀层的矫顽力出现极小值；Ｆｅ－Ｍｏ－Ｗ－Ｂ镀层矫顽力随退火温度的提高而连续增加。Ｆｅ－Ｓｎ－Ｂ和Ｆｅ－Ｗ－Ｂ镀层的剩磁比不

Abstract:

Fe TM B( TM =Sn, W, Mo W) alloy deposits have been prepared successfully using electroless plating. The magnetic properties of as plated and heat treated alloy deposits have been studied using vibrating sample magnetometry (VSM). The saturation magnetization of the alloy deposits increases with increasing iron content and decreases with increasing annealing temperature. The coercivities of Fe Sn B and Fe W B alloy deposits decrease to a minimum at 14 9 at.% B and 9 3 at.% B, respectively, and increase continually with increasing annealing temperature for Fe Mo W B. It has been also found that the ratio of remanence to saturation of the alloy deposits is not larger than 0 37 for Fe Sn B and Fe W B, and 0 53 for Fe Mo W B, furthermore it does not increase much even after heat treatment.
