Magnetron sputtering, vacuum arc deposition, and ion implantation have been used to create a three-layer anti-corrosive coating structure on stainless steel samples. The microstructure of the coating was analyzed using scanning and transmission electron microscopy. The chemical composition and concentration profile of the coating were determined using X-ray microanalysis. The structural-phase state of the coatings was studied using X-ray diffraction and electron diffraction analysis. The roughness of the experimental samples was determined using contact profilometry. The microhardness of the substrate and coating was determined using sclerometry. The salt spray corrosion tests and analysis of polarization curve have shown a significant increase in the corrosion resistance of stainless steel after deposition of a Ni/Cr/Al+B+ protective coating.
