| description | In this study, the effects of hydrogen on the electrochemical behavior and stress corrosion behavior of C110 steel in CO _2 environment was explored by electrochemical hydrogen charging, four-point bending stress loading and electrochemical test. The results show that with the raise of applied stress, the film resistance, transfer resistance of corrosion products decrease, and I _corr increases. After hydrogen charging, C110 steel has greater activity, and the combined action of external stress further promotes the corrosion reaction. The application of stress will destroy the formation of corrosion product film and reduce its protection. However, when the stress is further increased to 102% σ _s , the larger grains will be broken into smaller grains, so that the surface area of the film will be increased again and the protection of the substrate will be enhanced. The main corrosion products analyzed by XRD are α -Fe, Fe _2 O _3 and MgFe _2 O _4 . The applied stress will not change the phase composition of the corrosion products. |
