The corrosion behavior of pure zinc in tropic marine environment was simulated by cyclic immersion test, the correlation between cyclic immersion test and outdoor atmospheric test was evaluated qualitatively and quantitatively by comparing the corrosion morphologies, corrosion products and corrosion kinetics. The results show that the corrosion morphologies, compositions of corrosion products and corrosion kinetics after cyclic immersion test are in good correlation after the real atmospheric test. By Grey correlation method, using 2%NaCl solution to simulate Wanning atmosphere and using 5%NaCl solution to simulate Xisha atmosphere meet both simulation and acceleration. The corrosion life-span prediction method of pure zinc in two kinds of marine atmospheric environment is built by cyclic immersion experiments:Twn=95.23t1.01, Txs=841.60t0.16.
