中文摘要：在310S基体表面采用低压等离子喷涂（LPPS)技术制备MoB/CoCr金属陶瓷涂层。通过扫面电镜观察涂层的组织结构；测试了MoB/CoCr涂层的显微硬度和结合强度；用湿式橡胶轮磨粒磨损试验机测试涂层的磨损性能。结果显示：MoB/CoCr涂层组织为层状结构，涂层与310S基体之间、表面涂层与过渡涂层之间结合良好。MoB/CoCr涂层具有较高的硬度值和结合强度，且具有良好的抗磨粒磨损性能。
英文摘要：MoB/CoCr cermet coatings were deposited by low pressure plasma spraying (LPPS) on 310S steel. The microstructure of the MoB/CoCr coating was observed by SEM. The properties of microhardness and bond strength of the MoB/CoCr coating were tested. The abrasive wear properties were evaluated by MLS-225 wet sand rubber wheel tester. The results show that MoB/CoCr coatings are dense and have excellent combination with 310S steel substrate. MoB/CoCr coating has high hardness and excellent wear properties.
