The corrosion behaviour of Q235 steel in Qingdao and Wanning of China,the two kinds of polluted marine environment were simulated by cyclic immersion test, and the correlation of indoor cyclic immersion test and outdoor marine atmospheric corrosion test of Q235 steel were studied. The corrosion morphologies, corrosion products, corrosion kinetics of Q235 steel were investigated with methods of scanning electron microscopy (SEM), X-ray diffraction (XRD) and mass loss. The results reveal that the corrosion morphologies and compositions of corrosion products after cyclic immersion test agree with those after the real atmospheric test. Corrosion prediction model of Q235 steel in two kinds of marine atmospheric environment was built combined with Grey correlation method: T QD=137.002 t 1.093, T WN=102.398 t 0.952.
