【摘要】 以酒精和氢气为原料,用热灯丝辅助化学气相沉积法在不同表面状态的YG6硬质合金基休上生长了金刚石涂层,并对该涂层进行了激光拉曼光谱、X-射线衍射和扫描电镜分析。研磨试验表明,硬质合金表层钴含量和表面结构对金刚石涂层的结合强度有重大影响。硬质合金表层钻含量低、表面粗糙度高时,金刚石涂层的结合强度较高更多还原

【Abstract】 Diamond coatings were deposited on YG6 substrates with different surface characteristics by using HFACVD method, taking hydrogen and ethyl alcohol as raw materials. The formed diamond coatings were then examined by laser Raman spectroscopy, XRD and SEM. The grinding test results showed that the surface roughness and cobalt content strongly influened the adhesion of diamond coatings to the YG6 substrates. Lower cobalt content on YG6 surface and higher surface roughness resulted in better adhesion strength of diamond coatings to the YG6 hard alloy substrates.更多还原
