摘要:
利用纳米结构和常规喂料用大气等离子喷涂方法制备了Al2O3/TiO2涂层,研究了水环境中两种涂层与不锈钢对磨时的摩擦磨损性能.结果表明：水环境中,两种涂层摩擦因数变化不大,但是纳米喂料涂层耐磨性能明显优于常规涂层,同时其对偶的磨损率仅为常规涂层对偶磨损率的1/3～1/5,磨损率随载荷的增加不断增加.讨论了水环境中两种涂层的磨损机制.

Tribological Behaviour of Plasma Sprayed Al2O3/TiO2 Coatings From Nanoscale and Conventional Powders Under Water Environment
ZHAO Xiao-qin1,2，ZHOU Hui-di1, Chen Jian-min1
Abstract:
Two types of A1203/TiO2 coating with nano-scale and conventional powders were deposited by plasma spraying. Their wear mechanism against stainless steel as the counterpart of rubbing pair under water environment was discussed. The results showed that the friction coefficients of both coatings are similar at all test loads and exhibit no great difference. However, the coating with nanoscale powders improved wear resistance compared with coating with conventional powders, and also reduced wear rate of the counterpart material.
Key words:  tribology  plasma spraying  water environment  Al2O3/TiO2 coating
