稀土CeO2增强65Mn钢渗硼层的耐蚀性与抗磨性能
Rare Earth CeO2 Enhances the Corrosion Resistance and Wear Resistance of 65Mn Steel Boriding Layer
摘要
Abstract
At 700℃,rare earth boron co-permeation treatment was applied to 65 Mn steel.The microstruc-ture and characteristics of the surface coating were researched using metallographic microscope and energy dispersive spectroscopy(EDS).The effects on corrosion resistance and wear resistance were analyzed and compared with conventional boron treatment at 850℃.Corrosion and wear experiments were conducted to evaluate the corrosion resistance and wear resistance of CeO2-reinforced 65 Mn steel boronized layer in soil environment.The results showed that the structure of the coating became more uniform and dense after introducing CeO2 nanoparticles,which achieved a significant improvement in the corrosion resistance and wear resistance of the boronized layer.The corrosion test results showed that no cracks were found on the surface of the rare earth boron co-permeation coating,and it remained intact and dense with no signs of corrosion at the interface.The wear test results showed that the volume wear of the rare earth boron co-permeation coating was 18.09％of that of the conventional boron treatment.关键词
