For a long time, in actual production applications, people will cladding the coating to improve the wear resistance of the workpiece, but because the internal composition of the coating is uneven, the wear resistance life of the coating varies. High manganese steel (27SiMn) is usually used to prepare the components which works under a high load for long time.Therefore, this paper conducted research in this area. In order to improve the overall abrasion resistance of (Fe_0.25Co_0.25Ni_0.25Cr_0.125Mo_0.125)_xB_y high-entropy alloy (HEA) coating, laser cladding was used to prepare (Fe_0.25Co_0.25Ni_0.25Cr_0.125Mo_0.125)_xB_y high-entropy alloy (HEA) coating, the wear resistance between different sections was studied. X-ray diffraction, Vickers hardness tester, and friction and wear tester were used to analyze the phase composition, microhardness and wear resistance of the coating. After aqua regia corrosion, electron probes were used for microscopic morphology and element analysis. The experimental results show that (Fe_0.25Co_0.25Ni_0.25Cr_0.125Mo_0.125)₈₃B₁₇ coating with the cutting process, the microhardness and friction coefficient first increase and then decrease. (Fe_0.25Co_0.25Ni_0.25Cr_0.125Mo_0.125)₈₀B₂₀ coating with the cutting process, the microhardness gradually increases and the friction coefficient gradually decreases.The average microhardness of the laser clad B₁₇ coating is the highest in the second splitting, reaching 495.1 HV0.2. And the average microhardness of the laser clad B₂₀ coating is the highest in the third splitting, reaching 474.1 HV0.2. This is mainly because element segregation occurs during the laser cladding process, which makes the surface and internal wear resistance of the coating different.
