摘　　要：介绍了采用超音速火焰喷涂(HVOF)工艺结合物理气相沉积(PVD)技术在Cr_(3)C_(2)-NiCr涂层上沉积CrN涂层形成CrN/Cr_(3)C_(2)-NiCr复合涂层的强化工艺,并对复合涂层从薄膜微观结构设计、摩擦、腐蚀及减磨防腐机理方面进行了研究。The strengthening process of CrN/Cr_(3)C_(2)-NiCr composite coating formed by depositing CrN coating on Cr_(3)C_(2)-NiCr coating by high velocity flame spraying(HVOF)combined with physical vapor deposition(PVD)technology was introduced.The microstructure design,friction,corrosion and anti-wear mechanism of the composite coating were studied.
