Abstract — Corrosion and electrochemical properties of diffusion coatings on titanium formed by saturating from the carbon–oxygen-containing medium in aqueous 80% sulfuric acid solutions are studied. It is found that morphology of diffusion coatings affects the protective properties of titanium. It is shown that in extra-corrosive sulfuric-acid media carboxide coatings provide titanium with high protective properties, which exceed the corrosion resistance of carbide and oxide coatings.
