摘　　要：采用等离子喷涂Cr3C2-30%NiCr和WC-12%Co碳化物复合粉末制备具有高硬度、耐磨损、抗氧化等优点的金属/陶瓷涂层,用SEM研究大气等离子喷涂球形Cr3C2-30%NiCr和WC-12%Co粉末等离子喷涂涂层的显微组织及其对涂层机械性能的影响。结果表明,球形Cr3C2-30%NiCr和WC-12%Co粉末等离子涂层结合强度和表面硬度达到较好水平,WC-12%Co涂层机械性能均优于Cr3C2-30%NiCr涂层。The Cr3C2-30 % NiCr and WC-12% Co cabide coatings with excellent performances such as high hardness, anti-abrasion and oxidation resistance are prepared by APS process. The microscopic structures and their effects on mechanical properties of the coatings are analyzed by SEM. The experimental results show that coatings of spheric Cr3C2-30% NiCr and WC-12% Co powders produced by APS process are of high hardness and bond strength, and the mechanical properties of Cr3C2-30 % NiCr coating is better than WC-12% Co coating.
