TY - JOUR PY - 2021// TI - The corrosion behavior and cracking susceptibility of the disbonded coating in the X80 steel pipeline by theoretical simulations and experimental measurements JO - Corrosion reviews A1 - Zhao, Bo A1 - Zhao, Zhijuan A1 - Jin, Dong A1 - Li, Na A1 - Liu, Linlin A1 - Cao, Xin A1 - Shou, Binan SP - 573 EP - 587 VL - 39 IS - 6 N2 - The corrosion behavior and cracking susceptibility of the disbonded coating in the X80 steel pipeline were investigated by different methods. The oxygen content in the trapped solution decreased rapidly with the formation of an airtight disbonded area. The airtight system affected the electrode reaction process, resulting in the inhibition of corrosion in the center of the disbonded area and the more refined surface finish of the sample. The bottom of the disbonded area underwent a relatively intense and accelerated corrosion reaction controlled by the diffusion process. The cracking susceptibility of the X80 steel firstly decreased and then increased in the pointing direction. © 2021 Walter de Gruyter Keywords: Pipeline transportation
