摘要
采用低压等离子喷涂技术(LPPS)制备MoB/CoCr涂层,对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。
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.
