摘要
采用渗硼工艺对ＹＧ６硬质合金表面进行预处理，探讨了渗硼预处理对硬质合金金刚石薄膜涂层形成的影响。研究结果表明，渗硼时Ｃｏ在硬质合金表面同Ｂ形成ＣｏＢ、Ｃｏ２Ｂ化合物层。该硼化物层在金刚石沉积过程中，能有效阻挡硬质合金中粘结相Ｃｏ向表面扩散，消除了Ｃｏ对金刚石薄膜涂层形成时的不利影响，改善了薄膜涂层质量，提高了附着力。
A pretreatment way of boronizing on cemented carbide substrates to increase the adhesion of the diamond coating has been introduced in this paper A surface layer of stable cobalt borides was formed during boronizing,and this layer can hinder the Co migration when diamond films were deposited,and good morphology and adhesion of diamond coating has been obtained
