Corrigendum to “Effect of TiB2 content on the microstructure, corrosion behavior, and wear resistance of (Fe50Mn30Co10Cr10)0.8-x (TiB2)x Mo0.2 high-entropy alloy coatings by laser cladding” [Volume 496, 15 January 2025, 131662/ https://doi.org/10.1016/j.surfcoat.2024.131662]

The (Fe₅₀Mn₃₀Co₁₀Cr₁₀)_0.8-x(TiB₂)_xMo_0.2 (x = 0, 0.05, 0.1, and 0.2 at.%) HEA coatings were fabricated on a c steel substrate using laser cladding technology. To evaluate the effects of TiB₂ additions, this study conducted SEM and TEM microstructural characterization, XRD phase analysis, microhardness testing, friction and wear mechanical testing, and electrochemical corrosion testing. The results indicate that the dominant phase in the coatings is the FCC phase. The addition of TiB₂ inhibits the transition from the FCC to the HCP phase, resulting in the formation of σ and TiB₂ phases within the coatings. These boride phases enhance the wear resistance and hardness of the coatings through solid solution strengthening and second-phase strengthening. Furthermore, the presence of TiB₂ provides stable support for the passivation film on the coating surface, thereby enhancing corrosion resistance. However, an excessive amount of TiB₂ accelerates the formation and growth of the second phase, which acts as a surface defect. This significantly reduces the corrosion resistance of the coating and alters its wear mechanism, ultimately leading to a substantial decrease in wear resistance as well. The coatings exhibited the best overall performance in microhardness, wear resistance, and corrosion resistance at a TiB₂ content of 0.1 at.%.
