摘　　要：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磨损性能。研究结果表明,在钨极氩弧为热源的条件下,能获得性能较好的高温涂层,为碳化钨复合涂层在工业中的实际应用提供了理论基础。The WC granule is in- situ synthesized during the reaction of the alloy powders employing the TIG powder surfa- cing. The microstructure and morphology of the tungsten carbide coating is observed and analyzed. The elements of both the coating and the suhstrate diffuse to each other. The excellent metallurgy bonding is formed between the coating and the substrate. The results of the thesis show that we can get good performance of highm temperature coating by heating with TIG, which provides a theoretical foundation for the industrial practical application of WC composite coating.
