“…They are incredibly widely used in braking systems as well as engine systems. Such as brake discs, engine blocks, cylinder heads, and pistons in complex engineering applications [1][2][3][4][5][6][7][8]. As the application requirements of components continue to improve, it is difficult for the current practical application of aluminum matrix composites to meet the existing engineering applications in various aspects, such as wear-resistance [9,10].…”

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.
