The structure and physicochemical properties of chromium silicide coatings applied to carbon steel 20 have been studied. The diffusion coatings were obtained by the gas method. Corrosion studies showed that application of the coatings led to increased corrosion resistance in various industrially important aggressive media (3 % NaCl, solutions H₂SO₄, HCl, H₃PO₄, CH₃COOH, HNO₃).
