| 摘 要： | 模拟硬质合金Ｃｏ基胶结相的成分制备了二元Ｃｏ－Ｗ、Ｃｏ－Ｃ固溶体和三元Ｃｏ－Ｗ－Ｃ固溶体模拟合金，探讨了固溶成分影响比矫顽磁力Ｈｓｃ的规律．结果表明，Ｗ和Ｃ的固溶可分别提高和降低其Ｈｓｃ，影响程度随固溶度增加而加剧；由于Ｃ对Ｈｓｃ的影响较Ｗ更为强烈，导致Ｃｏ－Ｗ－Ｃ固溶体模拟合金的Ｈｓｃ低于纯Ｃｏ．

| Abstract: | The binary Co-W.Co-C and ternary simulative binder Co-W-C solid solutions were made by simulating the Co-base binder composition of cemented carbides. Then the relationship of specific corecive force Hsc of Co-base solid solutions vs. their component was explored. The results show that, W and C atoms can either raise or reduce the Hsc of the solid solutions respectively. Their effects on Hsc was intensified with the increase of the solubility of W or C in Co-base solid solutions. The Hsc of Co-base binder of cemented carbides is lower than that of pure Co because the effect of C on Hsc is more intensive than W. |
