The HEA-TiC high-entropy composite coatings with TiC (5, 10, 15 and 20 wt%) reinforced FeCoCrNiCu matrix were fabricated by laser cladding to investigate their tribological performances and wear behaviors at RT and 600 ℃. As the percentage of TiC particles elevated, the microhardness was progressively enhanced to 531.65 HV0.5 and its surface energy weakened to 24.29 mN/m. Whereas the excess TiC particles added into the coating internally appeared serious agglomeration, resulting in performance rebound. Fine-grain strengthening of high melting point and high hardness TiC acting as a heterogeneous nucleation site, precipitation strengthening of the Laves phase and dispersion strengthening of re-solidified carbides, and the blocking effect of TiC particles on dislocation motion. These reinforcing behaviors synergize to confer the desired tribological properties on the 15 wt% TiC coating, with outstanding wear resistance (7.6 × 10−6 mm3/N·m) at RT. The highly dense oxide film composed of TiO2 and the friction film reconstituted by Cr2O3 act synergistically on the coating surface at 600 ℃, the wear rate guided by oxidative wear is reduced by 88.7 %, compared to the TiC-free coating.
