    摘要:

    從孔隙的形成、界面非金剛石物的形成以及較高殘余應力等3個不利方面，分析和綜述了影響金剛石涂層與硬質(zhì)合金基體粘結(jié)性的主要因素。著重對浸蝕基體表面除去Co相或浸蝕WC相，在基體與涂層之間形成中間過渡層或中間化合物，基體表面機械或熱處理等硬質(zhì)合金基體表面預處理，改善涂層與基體粘結(jié)性的3種方法和途徑進行了闡述。

    Abstract:

    The poor adhesivity between diamond coating and cemented carbide substrate due to is the big difference in properties of diamond and cemented carbides, especially in the presence of Co in the substrate, which has the deleterious effect and brings about the transformation of diamond to amorphous and graphitic carbon. How to improve the adhesivity is very important for the products development of carbides with diamond film. The adhesivity can be improved by strictly controlling the process of diamond depostion, but the surface pretreatmetn of cemented carbide substrate is another more important approach to improve the adhesivity. The main factors effecting the adhesivity are briefly introduced, and the recent advances in the research of surface pretreatment of cemented carbide substrate for diamond coating are reviewed.
