| 摘 要： | 研究开发了一种FeAlCrNbB新型喷涂粉芯丝材,并结合自动化高速电弧喷涂工艺制备了该材料的复合涂层,分析了涂层的常规力学性能、组织结构和油润滑条件下的滑动摩擦磨损性能,并和常规FeAl涂层进行了对比。结果显示:FeAlCrNbB涂层具有相对较高的显微硬度和拉伸结合强度、低的孔隙率,组织致密,形成了由Fe-Al金属间化合物相、氧化物以及少量非晶和纳米晶组成的复合结构,由于这种复合结构的材料特征,使涂层具备较好的耐磨损性能。

| Abstract: | A new type of FeAlCrNbB cored wire is developed,and the intermetallic composite coating is prepared by using an automatic high velocity arc spraying technique.The general mechanical properties,microstructure and oil-lubricated sliding wear performance of the coating are investigated.The traditional FeAl coating is also investigated as a comparison.The results show that,as compared with the FeAl coating,the FeAlCrNbB composite coating is performed with higher micro-hardness and bonding strength,lower porosit... |
