The results show that a surface layer of stable cobalt borides of CoB, CoW2 B2 and CoW3B3 formed at 950 ℃ can effectively reduce the diffusion of Co to the surface of cemented carbide substrates when diamond films are deposited.

结果表明，基体经硼化预处理后表面形成CoB、CoW2 B2、CoW3B3相；当沉积温度为750~800 ℃，碳源浓度为3.3%时，薄膜表面形貌和生长织构随着沉积气压改变有明显的变化；硼化预处理后所得样品在1 500 N载荷下压痕表现出良好的附着性能，较二步法预处理更加有效地改善了膜基附着性能。
