Abstract
In this study, three composite coatings were prepared by laser cladding, selecting the ceramic particles (B4C, TiC, or NbC), together with the powders of high-entropy alloy (HEA), i.e. CrMnFeCoNi. The results demonstrate that the composite coatings reinforced by varied carbides exhibited special microstructures, which lead to the features of micro-cutting wear, three-body wear, and fatigue wear, respectively. Therefore, the differences between the three composite coatings were compared, and evaluated in terms of phase structure, microstructure, chemical composition, nanoindentation, and phase interface correlation. Ultimately, the wear resistance mechanisms of selected ceramic particles reinforced HEA coatings were explained, and their applicability was estimated.
