%X The cathodic delamination behaviour of a tar epoxy organic coating on 16Mn and CCSB steel under the simultaneous action of constant amplitude cyclic loading and corrosive medium has been studied. The variation of coating delamination area with time was examined under different loading conditions at \|1600mV(SCE). The effect of steel substrate on the cathodic delamination behaviour of the coating has been also investigated. The evolution of cathodic current under different conditions was measured with delamination time. The results revealed that the coating had a good resistance to cathodic delamination without applied loads, but under cyclic loading condition, this resistance greatly decreased beacuse of the effect of stress and local strain concentration on medium transport and interfacial situation of the coating, the degree of the decrease was enhanced with increasing stress level. \=
