摘　　要：对比三种不同工艺(高频感应熔涂、激光熔覆、氧乙-炔喷焊)制得的GNi-WC25涂层的性能。结果表明,高频感应熔涂GNi-WC25涂层的表层硬度、耐磨性和耐腐蚀性均优于激光熔覆涂层和氧乙炔喷焊涂层,而且高频感应熔涂涂层表面平整,后续加工量较少。The properties of GNiWC25 coating by high frequency induction cladding, laser cladding and oxygenacetylene sprayingfusing was investigated The results show that the surface hardness, wearresistant and corrosionresistant properties of GNiWC25 coating have an advantage over those of laser cladding coatings and oxygenacetylene sprayingfusing coatings Moreover, the GNiWC25 coating by high frequency induction cladding has the smooth surface which needs less furtherprocessing
