中文摘要：

采用低压等离子喷涂技术（LPPS）制备MoB／CoCr涂层，时涂层进行磨粒磨损试验研究。采用SEM观察涂层的表面和截面形貌，显微硬度计测试涂层的力学性能，湿式橡胶轮磨粒磨损试验机测试涂层的磨粒磨损性能。结果表明，涂层组织致密，呈层状结构；涂层具有良好的力学性能，显微硬度达到930HV0．3，结合强度在71MPa以上，具有较高的耐磨性能。

英文摘要：

MoB/CoCr coatings were prepared by low pressure plasma spraying（LPPS）, the abrasive wear experiment was investigated, The surface and cross sectional morphologies of the MoB/CoCr coatings were observed by SEM. The properties of microhardness and bond strength of the MoB/CoCr coatings 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 mechanical properties with high microhardness（930HV0. 3） and bond strength（71MPa）. The MoB/CoCr coatings have high abrasive wear resistance property.
