Abstract This study investigates the effectiveness of Cu as a corrosion barrier in supercritical carbon dioxide (s−CO2) by coating 316 stainless steel (316) with various thicknesses of Cu. 316 exposed to s−CO2 with 50 ppm CO showed a reduction in oxidation corresponding to the thickness of its Cu barrier coating. Additionally, a continuous Cu layer between the environment and the alloy was found to correlate to an elimination of carburization and corrosion-related mechanical degradation. This Cu coating technique could be applied over a variety of temperatures to improve the corrosion resistance of alloys that are susceptible to carburization.
