The results of a study of the structure ard properties (microhardness, internal stresses, and magnetic characteristics) of electrolytic Fe-Ni coatings deposited from sulfate and chloride electrolytes of various compositions onto polished Cu sections are presented. The phase composition was determined by x- ray diffraction. The hardness of the Fe-Ni coatings proved to be greater than the hardness of Fe and Ni deposits (especially from sulfate solutions) and approaches the hardness of electrolytically deposited Cr. Electrolytically deposited Fe-Ni alloy cxhibits high internal stresses owing to the distortion of the lattice parameters, possesses a very fine crystalline structure and luster, and constitutes a solid Fe-Ni solution. Electrolytically deposited alloys cxhibit a higher coercive force and a lower residual induction than rolled and heat-treated alloys. The great hardness, the beautiful appearance, and a sufficiently high corrosion resistance of coatings containing up to 30% Fe provide a basis for the assumption that they might replace nickel and sometimes even chromium coatings.
