| 摘 要： | 为了获得质量较好的喷焊层，提高喷焊层的耐磨性，在镍基自熔性合金粉末F102中加入不同体积分数的亚微米碳化钨（WC）进行氧一乙炔火焰喷焊．通过磨粒磨损试验、显微硬度测试和显微组织分析，研究了不同WC体积分数对喷焊层质量及其耐磨性的影响．试验结果表明WC的体积分数为1％时，喷焊层的质量最优，耐磨性最好，硬度也最高．但随着WC体积分数的进一步增加，喷焊层的耐磨性和硬度反而有所下降．涂层的耐磨性主要与涂层硬度．WC硬相的含量，空洞的数量及大小等有关．硬度越高，WC硬相越多，空洞越少、越小，涂层的耐磨性越好，反之越差．

| Abstract: | Flame spray was carried out by mixing different content of WC into self-fusing F102 metal powders.The influences of WC content upon wear resistance of sprayed coating were studied through testing of macroscopic hardness,low-stress abrasive particle wear resistance and analyse of microstructure of sprayed coating.The results show that when the volume content of WC is 1%,the quality of the coating is the best.With the volume content of WC increasing, the wear resistance and hardness decrease.superfine WC;wear resistance;flame spray;abrasive particle wear;volume content |
