Abstract

Coatings based on cobalt-manganese spinel (Mn, Co)·(Mn, Co)2O4 were obtained on the surface of stainless steel by polarization with alternating asymmetric current. The study of the mechanical properties showed that the coatings are characterized by a sufficiently high adhesion to the substrate, their thickness is about 30 μm, and the microhardness value is 40 HV, which is comparable to similar oxide materials. The study of thermal stability in air shows their stability at temperatures up to 1000 °C, and the study of corrosion-protective properties - about the stability of the resulting coatings in a solution of 3.5% (wt.) NaCl.
