陶瓷涂层的火焰喷涂及其耐磨性能

Flame Spraying Ceramic Material and Spraying Coat’s Wear Behaviour

本文介绍了采用氧乙炔火焰喷涂Ａｌ２Ｏ３－ＴｉＯ２陶瓷材料。对其耐磨性能和机理进行的试验研究结果表明，在Ａｌ２Ｏ３中加入一定量的ＴｉＯ２不仅使Ａｌ２Ｏ３可以采用氧乙炔火焰喷涂，并且涂层的孔隙率下降，抗压强度增加，耐磨性能提高。

Oxygrn-acetylene f1ame spraying A12O3-TiO2 ceramic material is introduced,and spraying coat’s wear behaviour and mechanism are studied.The results show that Al2O3 ceramic material with some quantity of TiO2 can be sprayed by oxy-acetylene flame, and spraying coat's wear behaviour and comprereive resistance are increased,porosity is decreased.
