Passivation of X65 (UNS K03014) carbon steel in NaHCO 3 solution in a CO 2 environment
Source abstract
Abstract
Abstract In this study, the use of NaHCO 3 as a pH stabilizer for the corrosion control of X65 (UNS K03014) carbon steel in different environments was experimentally investigated. The experiments were conducted at room temperature and at 50 °C in 0.5 M NaHCO 3 solutions purged with CO 2 . Electrochemical tests were conducted in a high-pressure, high-temperature autoclave. The constituents of the corrosion products were investigated through scanning electron microscopy and X-ray diffraction. The results showed that X65 steel can be passivated in 0.5 M NaHCO 3 solution in a CO 2 environment. Immersion in 0.5 M NaHCO 3 solution in a high-pressure, high-temperature autoclave resulted in the formation of a dense corrosion film on the surface of the X65 steel.
