摘要
利用激光熔覆技术在铝基复合材料表面制备了 FeCuMoTiV 高熵合金涂层。详细研究了涂层的物理相组成、各物理相的硬度以及涂层的摩擦和磨损行为。研究结果表明从 XRD 和 TEM 分析来看,涂层的物理相 BCC1(MoV)和 BCC2(TiFe)是一致的。从 EBSD 分析来看,涂层的晶粒没有明显的选择性取向,平均等效圆直径为 26.44 μm。纳米力学测试表明,涂层中 BCC1 相的平均硬度为 7831.2 N mm-2,使涂层具有优异的耐磨性。涂层的平均摩擦系数随着时间的延长呈先减小后增大的趋势,在 0.3 ± 0.05 的范围内浮动。涂层在磨损表面形成了含有 Fe2O3、MoO3、CuO 和 TiO2 混合氧化物的 "釉层 "结构,具有良好的润滑性。结合 SEM 分析,涂层的磨损机理是磨料磨损、氧化磨损、粘着磨损和疲劳磨损的混合。
Wear performance of FeCuMoTiV high entropy alloy coatings by laser cladding
FeCuMoTiV high-entropy alloy coatings were prepared on the surface of aluminum matrix composites using the laser cladding technique. The physical phase composition of the coating, the hardness of each physical phase, and the friction and wear behavior of the coating were studied in detail. The results show that: From the XRD and TEM analysis, the coating’s physical phases, BCC1(MoV) and BCC2(TiFe), are coherent. From the EBSD analysis, the grains of the coating have no obvious selective orientation, and the average equivalent circle diameter is 26.44 μm. Nanomechanical tests showed that the average hardness of the BCC1 phase in the coating was 7831.2 N mm−2, which provided the coating with excellent abrasion resistance. The average coefficient of friction of the coating showed a tendency to decrease and then increase with the increase of time, and it floated in the range of 0.3 ± 0.05. The coating forms a structure containing Fe2O3, MoO3, CuO, and TiO2 mixed oxide ‘glaze layer’ on the wear surface, which provides good lubrication. Combined with SEM analysis, the wear mechanism of the coating is a mixture of abrasive wear, oxidative wear, adhesive wear, and fatigue wear.
