Abstract: The results of a study of the microstructure and magnetic properties of nanostructured coatings made of high entropy FeCoNi(P)–$Me$ ($Me$ = Zn, Zr, W) alloys synthesized by chemical deposition are presented. The phase- structural state of the coatings has been studied by X-ray diffraction and electron microscopy. The magnetic characteristics of the synthesized materials (saturation magnetization, coercive force, local anisotropy fields) were studied as functions of the Zn, Zr, or W content in the FeCoNi(P)–$Me$ alloy. The magnetic properties are discussed within the framework of the random magnetic anisotropy model. The boundary values of entropy and enthalpy of mixing have been determined, which contribute to the formation of an unordered solid solution in the production of high-entropy alloys based on FeCoNi(P) by chemical precipitation.

Keywords: high-entropy alloys, coatings based on FeCoNi(P), chemical deposition, magnetic properties, entropy of mixing.
