摘要

摘要采用高能量密度气体钨极电弧焊(GTAW)在低碳钢表面制备FeMn、FeB和石墨粉末。采用x射线衍射、光学显微镜、能量色散x射线分析、扫描电镜、显微硬度计和黏着磨损试验等方法研究了复合涂层的显微组织、硬度和干滑动磨损行为。在涂层表面发现了多种不同的碳化物和硼化物，包括Mn5C2、Fe3C、B8C、MnB、B4C、Fe3B、Fe7C3、FeB和Mn2B。显微组织分析表明，石墨的形状也与FeMn-FeB-C含量有关。样品S4的失重最小，在氧化向磨料转变过程中，加入5% ~ 20% wt%的石墨可以提高临界滑动距离。

Adhesive wear behavior of FeB–FeMn–C coatings produced by GTAW

Abstract In this paper, a high energy density beam of gas tungsten arc welding (GTAW) was employed to build a surface over low carbon steel with FeMn, FeB, and graphite powders. X-ray diffraction, optical microscopy, energy dispersive X-ray analysis, scanning electron microscopy, micro hardness tester, and adhesive wear tester were used for researching behavior of the composite coating which microstructure, hardness and dry-sliding wear. Many different carbides and borides, including Mn5C2, Fe3C, B8C, MnB, B4C, Fe3B, Fe7C3, FeB, and Mn2B, were found on the coated surfaces. The microstructure analysis shows that the shape of the graphite also depends on the FeMn–FeB–C content. The smallest weight loss was obtained from Sample S4 and the critical sliding distance was enhanced by adding graphite from 5 to 20 wt% at transition from oxidative to abrasive.
