Abstract

To improve the wear resistance of the FeCoCrNiB_0.2 high entropy alloy (HEA), the FeCoCrNiB_0.2 (WC₀) and FeCoCrNiB_0.2 + 20wt% WC (WC₂₀) HEA coatings were prepared on Q235 steel by laser cladding (LC). The microstructure, hardness, and tribometer of the HEA coatings were investigated using scanning electron microscopy with spectroscopy (SEM/EDS), X-ray diffraction (XRD), vickers microhardness tester, and pin-on-disc tribometer, respectively. The experimental results show that the WC₀ HEA coating comprises a simple BCC phase mixed with an M₂B phase. Adding 20wt% WC, the WC₂₀ HEA coating is composed of a simple BCC phase mixed with the Cr₂₃C₆ carbide phase. The microstructure of the WC₂₀ HEA coating is simple, which consists of equiaxed grain and dendritic. The microhardness also increases from 625.5HV to 806.0HV, and the wear mass loss correspondingly decreases from 30.9 to 14.9 mg. W and C atoms formed by WC dissolution are mainly dissolved in the BCC phase, which leads to the solution strengthening effect. Besides, Cr₂₃C₆ carbides inhibit the growth of the grains, play the role of fine-grain strengthening, and further improve the hardness and wear resistance of the HEA coating.
