利用氧乙炔火焰喷涂工艺，在纯铜表面反应形成高硬度、高耐磨性的 TiO2/Cu 梯度复合涂层。试验结果表明，火焰喷涂反应生成 TiO2/Cu 梯度涂层为典型波浪状多层喷涂组织，涂层组织呈梯度连续变化，梯度层间结合情况良好，无明显界面；涂层与基体有明显的宏观层间界面，结合情况较好。火焰喷涂反应生成的TiO2/Cu 梯度涂层中存在气孔、夹杂等缺陷。
利用氧乙炔火燄噴塗工藝，在純銅錶麵反應形成高硬度、高耐磨性的 TiO2/Cu 梯度複閤塗層。試驗結果錶明，火燄噴塗反應生成 TiO2/Cu 梯度塗層為典型波浪狀多層噴塗組織，塗層組織呈梯度連續變化，梯度層間結閤情況良好，無明顯界麵；塗層與基體有明顯的宏觀層間界麵，結閤情況較好。火燄噴塗反應生成的TiO2/Cu 梯度塗層中存在氣孔、夾雜等缺陷。

The reactive TiO2/Cu FGC with a gradual compositional variation from Cu substrate to TiO2 ceramic surface was made by flame spraying. Experimental results show that the reactive TiO2/Cu FGC made by flame spraying presents a typical wavy multi-layer structure, the coating is gradually transited along the direction of the coating and the bond among the gradient layers, without distinct interfaces. The bond between the coating and the substrate is also well, but there is distinct macro-interface between them. There are small defects in the reactive TiO2/Cu FGC, such as gas hole, impurity, and so on.
