CoCrFeMoNiSix (x = 0.25, 0.50, 0.75) HEACs were successfully prepared on Q235 steel substrates by the plasma cladding method. The phase structure, microstructure, element distribution, and wear corrosion resistance of these coatings investigated XRD, OM, SEM, EDS, a friction tester, an electrochemical workstation. results show that are composed major FCC minor BCC phase. With increase in Si content, lattice constant cell volume both phases content alloys gradually increase, while enthalpy mixing, Gibbs free energy, atomic radius difference, VEC, density decrease. All three exhibit typical dendritic structures. enrichment Mo interdendrite region is significantly reduced. coefficients trend first increasing, then decreasing, stabilizing with time, 0.604, 0.526, 0.534, respectively. mainly related to changes crystallinity high-strength caused different contents. polarization curves high-entropy alloy obvious passivation zone, better than substrate. CoCrFeMoNiSi0.75 coating has highest self-corrosion potential, smallest current, largest capacitive reactance arc radius, best 3.5% NaCl solution.
