| 摘 要： | 等离子熔-喷技术同时具备等离子喷涂、熔焊技术的综合特点，可以实现各种陶瓷材料涂层与基体的冶金结合。Co基WC具有硬度高、耐磨损、耐腐蚀、耐高温等一系列优点。采用等离子熔-喷技术在Q235钢基体表面制备WC-17％Co涂层，通过研究等离子熔-喷工艺参数（等离子熔枪和喷枪角度、熔枪和喷枪与基材表面的距离、熔-喷速度、喷涂送粉量）对涂层外观形貌的影响，获得最佳的工艺参数，制备出外观形貌良好、无缺陷的熔-喷涂层。

| Abstract: | Ceramic coatings can be metallurically bonded to metal sabstrate with plasma-melt-spraging, which has virtue of both plasma spray and harfacing. Coralt-based WC is hard, wear-reristant, corrosion-resistant and thermal-resistant. WC-17% Co coating was plasma-melt-sprayed on Q235 substrate. Influnce of proceis parameters ( angle between plasma melting torch and spraying torch, distance between the plasma torch and the substrate, velocity of melting and spraying and feeding rate of powder) on appearamce of the coating was investigated, and the pavameters were optimized. Metallurgically bonded coating withoutdefects was obtained. |
