利用粉末热喷涂法制备（Ｎｉ，Ｃｒ）／Ａｌ２Ｏ３复合涂层，采用ＸＲＤ和金相对复合涂层的相结构和相组成进行分析，并分析了喷涂工艺对金属／陶瓷系复合涂层制备的影响。实验结果表明，Ａｌ２Ｏ３粉末的沉积率和喷涂参数是影响（Ｎｉ，Ｃｒ）／Ａｌ２Ｏ３复合涂层相结构和相组成的关键。
The (Ni, Cr) / Al2O3 composite coating was prepared by powder thermal spraying method. The phase structure and phase composition of XRD and gold relative composite coating were analyzed. The effect of spraying process on the preparation of metal / ceramic composite coating was also analyzed . The experimental results show that the deposition rate and spraying parameters of Al2O3 powder are the key factors influencing the phase structure and phase composition of (Ni, Cr) / Al2O3 composite coatings.
