应用 X射线衍射、X-光电子谱和扫描电镜研究了金刚石薄膜与W、WC-6 % Co硬质合金基体间的界面结构。指出在 W基体和金刚石薄膜之间存在 W的碳化物界面 ,WC-6 % Co硬质合金经表面腐蚀去 Co处理后仍能形成不连续非金刚石碳界面 The interfacial structures between diamond films and W, WC-6% Co cemented carbide substrates were investigated by X-ray diffraction, X-ray photoelectron spectroscopy and scanning electron microscopy. It is pointed out that there is a W carbide interface between the W matrix and the diamond film, and the WC-6% Co cemented carbide can still form a discontinuous non-diamond carbon interface after surface-treated with Co
