对１６Ｍｎ钢与ＣＣＳＢ钢表面环氧沥青基有机涂层在常幅交变应力与腐蚀介质共同作用下的阴极剥离行为进行了研究．结果表明，在没有外加应力条件下，涂层具有良好的界面粘附性；而在交变载荷作用的条件下，应力与局部应变集中通过影响有机涂层的介质传输与界面状态，使有机涂层在介质中的阴极剥离抗力显著降低，降低幅度随外加应力水平而升高 The cathodic disbondment behavior of the epoxy-based organic coatings on 16Mn steel and CCSB steel was studied under the action of normal amplitude alternating stress and corrosive media. The results show that the coating has good interfacial adhesion under the condition of no external stress. Under the condition of alternating load, the stress and local strain are concentrated and the organic coating The cathodic disbondment resistance of the layer in the medium is significantly reduced, and the decrease amplitude increases with the applied stress level
