摘　　要：碳化钨陶瓷因具有极高的熔点、高的化学稳定性、高的硬度和优异的耐磨耐蚀性,已成为近年来金属陶瓷研究的热点之一。笔者采用钨极氩弧堆焊设备,通过原料粉末之间的高温冶金反应,在堆焊过程中原位合成碳化钨金属陶瓷涂层,对所制备的涂层试样的组织结构进行了观察分析,并且研究了涂层的耐磨料的磨损性能。As a typical boride ceramics,WC ceramics have become a researched hot point because of its high melting point,good chemi- cal stability,high hardness and good resistance to abrasion. The WC granule is in situ synthesized during the reaction of the alloy powders employing the TIG powder surfacing. The microstructure and morphology of the tungsten carbide coating is observed and ana- lyzed. The abrasive wear performance of the coating is also studied.
