摘要
采用粉末冶金工艺制备纯铁磁粉芯,研究了粘结剂含量、组成对磁粉芯综合性能的影响。结果表明,粘结剂含量为2.7%～3.6%,无机与有机粘结剂组成为3∶2～3∶1时,粘结剂的包覆效果较好,样品的力学性能得到较大改善,抗压强度达到了480 MPa;粘结剂含量为2.8%～3.5%,无机与有机粘结剂组成为2∶1时,磁粉芯磁性能较好,综合性能较佳。
Pure iron powder cores were fabricated by powder metallurgy technique. Influence of the content and composition of binders on comprehensive performance of the material was researched. Result shows that the mechanical properties of samples are greatly improved and the compressive strength achieves 480 MPa when the total content of binders is 2.7%- 3.6% ,inorganic and organic ratio are 3 ： 2-3 ： 1 ,as binder coating get the best effect. Magnetic properties and comprehensive performance of magnetic cores are the best when total content of binders is 2.8%-3.5% ,inorganic and organic ratio is 2： 1.
