One of the main problems of the use of stainless steels is related to low strength of steels to pitting corrosion in chloride-containing environments such as sea water. In this paper, the corrosion resistance of the cerium oxide coating on stainless steel is investigated. Potentiodynamic polarization and impedance spectroscopy was used to study the corrosion behavior of the coating. In addition, microstructural and phases of the cerium oxide coatings were studied using a scanning electron microscope, FTIR and X-ray diffraction. The results showed that the formation of cerium oxide coatings on the stainless steel causes an increase in the corrosion resistant and the best corrosion resistant of the coating was obtained when the heat treatment was applied at 300 ° C.
