摘　　要：利用自蔓延(SHS)反应火焰喷涂技术,以(CuO–Al)为反应主体系,设计了具体工件表面修复Al2O3陶瓷涂层的工艺。通过对陶瓷涂层的孔隙率、结合强度、耐磨损性能测试及实际应用表明,该工艺能够满足工件表面修复技术的需要,为该技术在具体工件上的实际运用提供了借鉴。The technology was designed that Al2O3 ceramic coating was prepared to repair the specific workpiece surface through the SHS reaction flame spraying with CuO-Al being the main reaction system. The performance test of porosity,bond strength,microhardness and abradability and the practical applications showed that the technical requirements of surface repairing were satisfied. And many references were provided for the practical applications.
