| 摘 要： | 采用火焰喷涂-感应重熔工艺在45钢基体上制备铁-铝金属间化合物涂层,对其退火热处理工艺进行正交设计,得出优化的工艺为750℃退火1.5 h。优化退火后涂层的磨屑及磨损后试样表面形貌分析表明:涂层的主要磨损机制开始为粘着磨损,随后转变为磨粒磨损。由扫描电子显微镜分析可知:退火后铁-铝金属间化合物涂层由固溶体、条块状碳化物、氧化物和孔隙组成。

| Abstract: | Fe-Al intermetallic compound coating was prepared on 45 steel substrate by flame spraying-induction remelting. The annealing technics was optimized by orthogonal experiment design, as annealing at 750 ℃ for 1.5 h. The wear mechanism of the coating, revealed by abrasive dust analysis and surface observation after wear, was the adhesive wear at the beginning followed by the abrasive particle wear. The microstructure of the annealed Fe-Al intermetallic compound coating was composed of solid solution, strip shaped and massive carbides, oxides and pores, as analyzed by SEM-EDS. |
