| 摘 要： | 用大气等离子喷涂(APS),超音速火焰喷涂(HVOF)和冷喷涂(CS)在镁合金表面制备316L涂层。用SEM及X射线衍射仪分析原始粉末及涂层的形貌和显微组织,用摩擦磨损试验机和电化学试验机考察涂层的摩擦磨损及耐蚀性。结果表明:3种工艺制备的涂层耐磨性和耐蚀性均优于镁合金基体,CS涂层具有最高的硬度及最优异的耐蚀性,但磨损率略高于APS涂层,CS涂层的整体性能更好,对镁合金等轻质合金表面强化的潜力更大。

| Abstract: | 316L stainless steel coatings have been applied on the surface of magnesium alloy using atmospheric plasma spraying(APS),high-velocity oxygen fuel(HVOF)and cold spraying(CS)respectively. SEM and XRD were used to characterize the original powder and 316L coatings morphology and microstructure. Friction and wear properties and corrosion properties of the coatings were investigated by tribometer and electrochemical test machine. The results show that the wear resistance and corrosion resistance of the coatings prepared by the three processes are superior to the magnesium alloy matrix,and the CS coating has the highest hardness and the best corrosion resistance,but the wear rate is slightly higher than that of the APS coating. The overall performance of the CS coating is better,and it has greater potential for surface strengthening of light alloys such as magnesium alloys. |
