采用火焰喷涂和熔凝工艺在碳钢表面制备了不同CeO 2含量的镍基合金涂层。在干滑动、环境条件下，使用球-平磨损试验机研究了涂层的摩擦学行为。采用硬度测试、场发射扫描电镜及能谱仪、振动摩擦磨损试验等手段对涂层的显微硬度、微观结构及摩擦学性能进行了表征。结果表明，适量CeO 2的加入可以细化和净化合金的组织。含5wt%CeO2的涂层具有最高的耐磨性能。此外，一个新的化合物相，Ce 2Ni 21 B6，形成的涂层内，这样的显微硬度值包含此相是高于那些在其他涂层。最后，讨论了CeO 2对涂层的影响及其滑动磨损机理。
In this work, Ni-based alloy coatings with different CeO2rare earth oxide contents were deposited on carbon steel by flame spray and fusing processing. The tribological behavior of the coatings was studied using a ball-on-flat wear tester under dry sliding, ambient conditions. Hardness testing, field emission gun scanning electron microscopy with attached energy dispersive spectroscopy and oscillating friction and wear testing were employed to characterize the microhardness, microstructure and tribological properties of the coatings. The results indicated that the addition of an appropriate amount of CeO2could refine and purify the microstructure. The coatings containing 5 wt% CeO2exhibited the highest wear-resistant properties. Moreover, a new compound phase, Ce2Ni21B6, was formed within the coatings, such that the microhardness values containing this phase were higher than those in the other coatings. Finally, the effects of CeO2on the coatings and the mechanism describing the sliding wear were discussed.
