The aim of this paper is to investigate the role of the poly (vinyl alcohol) film, doped with strontium ranelate, on the corrosion behavior of stainless steel in contact with physiological serum. The corrosion behavior was studied using two electrochemical methods: the Tafel polarization and the polarization resistance. The small current densities and high polarization resistances were obtained for stainless steel surfaces covered with PVA doped with strontium ranelate, electrochemically deposited from 0.1 M HCl solutions. It was found that the protection efficiency increased when stainless steel was electrochemically modified with strontium ranelate.
