摘　　要：利用扫描电子显微镜和X射线衍射分析仪研究喷涂距离和氧燃率对爆炸喷涂WC-Co涂层性能的影响。结果表明,WC-Co涂层的最佳爆炸喷涂距离为110 mm,氧燃率为1.06。WC-Co涂层结构致密、耐磨性好,拥有近似各向同性的特征。The effect of spraying distance and oxygen combustion rate on properties of WC-Co coating was studied by SEM and XRD. The results show that the optimum explode spraying distance is 110 ram, and the optimum oxygen combustion rate is 1.06. The structure of the coating is dense and have good wear resistance, which shows similar isotropic characteristics.
