摘要
对水环境中PA1010、PEEK、TX和NSM分别与激光熔覆合金表面和等离子喷涂ZrO_2·MgO陶瓷表面的磨损特性进行了试验,发现PEEK与两种对偶材料的磨损量最小,TX次之,PA1010和NSM的磨损量与对偶材料关系较大,前者与陶瓷组合时磨损量剧增,后者与激光熔覆盘组合时磨损量较大。分析表明工程塑料与激光熔覆表面的磨损机理以机械切削为主,与陶瓷涂层的磨削以塑性转移为主。
The wear characteristics of PA1010, PEEK, TX and NSM with laser cladding layer (LCL) and plasma-sprayed engineering ceramic surface (SSC) respectively are tested under water surroundings. It is found thai the wear of PEEK is the least with both the materials, next is TX, whereas the wear features of PA1010 and NSM vary with the matching materials. The former's wear increases drastically with SSC, and the latter wears more with LCL. Further analysis shows that the wear mechanism of engineering plastics with LCL is mainly mechanical cutting, while with SSC is plastic transfer.
