【摘要】 用矛盾论的观点与方法 ,分析论述了硬质合金制造与使用过程中的矛盾运动。指出硬质相与粘结相的对立统一是硬质合金中贯穿始终的基本矛盾 ,碳量控制则是硬质合金生产的主要矛盾 ,抗弯强度是各种矛盾因素综合作用的产物。如何利用矛盾规律来指导硬质合金的科研与生产 ,是值得探讨的一个问题。更多还原

【Abstract】 Contradiction movement in cemented carbide has been analysed and discussed with viewpoint and method of contradiction in the paper.It is pointed out that the unity of opposites between hard phase and binder phase is basic contradiction ran through cemented carbide.Carbon content controling is principal contradiction in prodwction of cemtnted carbide.Transverse rupture strength is the products of comprehensive action of various contradiction factors.How to use the law of contradiction to direct the scientific research and production is a problem which is worth exploration and paid more attention.更多还原
