Abstract Scope Carbon capture and storage (CCS) technologies can decrease the greenhouse gases emissions. Compression pumps for moving and pressurizing the captured CO2 requires high strength and elevated corrosion resistance due as-captured CO2 is not pure, usually containing residual water and small amounts of NOx and SOx contaminants, which can form a liquid phase containing sulfuric and nitric acid. Therefore, it is important to create a materials database for these environments. In this study, the corrosion resistance of wrought 17-4PH stainless steel was investigated in CO2 saturated aqueous solution with and without acid addition (HNO3 and H2SO4). The same experiments are being repeated using additive manufactured samples. Weight-loss experiments showed that HNO3 addition has a negligible effect on corrosion resistance of 17-4PH, unlike H2SO4 addition, which increased significantly the corrosion rate of steel. However, electrochemical results showed that samples in H2SO4 reaching the same impedance of samples in HNO3 after 24 hours.
