研究了等离子喷涂法制备ＺｒＯ２Ｔｉ系功能梯度涂层。结果表明，采用等离子喷涂工艺制备功能梯度涂层是可行的，涂层与基体除以机械咬合方式结合外，还存在着少量冶金化学反应结合，添加Ｎｉ／Ａｌ和ＳｉＯ２有助于提高涂层的结合强度 The ZrO2Ti system functional graded coatings were prepared by plasma spraying. The results show that it is feasible to prepare functional graded coating by plasma spraying. In addition to the combination of the coating and the substrate by mechanical occlusion, there is still a small amount of metallurgical chemical reaction. The addition of Ni / Al and SiO2 helps to improve the coating Bond strength
