The phase composition and corrosion-electrochemical properties of Fe5CrCuNiMnSi and Fe5CоCuNiMnSi spalt-quenched high-entropy alloy films were studied. The alloy films were fabricated by a known technique of splat-quenching. A cooling rate estimated by film thickness was ~ 106 K/s. The electrochemical behavior and corrosion resistance was determined in a neutral solution of sodium chloride. Using X-ray diffraction analysis, the phase composition and crystal lattice parameters of the investigated high-entropy alloy films were determined. It was established that both Fe5CоCuNiMnSi and Fe5CrCuNiMnSi spalt-quenched high-entropy alloys are solid solutions with a face-centered cubic lattice. The values of stationary potentials and areas of electrochemical stability of alloys, as well as the density of corrosion currents, are determined. It has been shown that samples of the Fe5CrCuNiMnSi alloy behave inertly in corrosion tests. The obtained results also were compared with the characteristics of similar alloys obtained by casting.
