| 1 | Corrosion behavior of 13Cr stainless steel under stress and crevice in high pressure CO_(2)/O_(2)environment显示文摘In this work,through the self-developed setup for in situ electrochemical tests,the corrosion behavior of 13 Cr stainless steel under the combined effect of stress and crevice in high pressure CO_(2)/O_(2)environment was investigated.The results show that 13 Cr stainless steel presents a self-passivation state.Under the action of stress,the anodic dissolution process of steel inside crevice is expedited.There is a galvanic effect between the stressed steel inside crevice and the unstressed steel outside crevice.The applied stress reduces the induction stage of crevice corrosion and induces a larger galvanic current,i.e.,the applied stress promotes the development of crevice corrosion.Meanwhile,adding 0.1 MPa O_(2)is conducive to forming a more stable passive film but causes a greater galvanic effect. | G.Y.Zhu Y.Y.Li B.S.Hou Q.H.Zhang G.A.Zhang | 2021 | Journal of Materials Science & Technology2021，，29： | 1 |
