| 摘 要： | 研究了等离子喷涂粉末沉积率对功能梯度涂层的结合强度影响，结果表明，在设计比例下，由于ZrO2的沉积率低，使涂层表面纯陶瓷层与次表层的成分梯度增大，应力梯度增加，导致界面结合变弱，涂层结合强度降低，通过增加次表层ZrO2含量，可较大幅度增加涂层的结合强度。

| Abstract: | WT5BZ]The effect of powder deposit efficiency of plasma spray on combinative intensity of functionally gradient coatings is studied Tle results show that deposit efficiency of ZrO 2 is lower than Al/Ni,so the grads of component and stress between surface layer and the secondary one is more apparent increased,the combine of interface is more weakly and the combinative intensity of coatings is lower Increase the content of ZrO 2 in secondary layer can get the higher combinative intensity of coatings |

| Keywords: | plasma spray depoit efficiency functionlly gradient coatings combinative intensity |
