Abstract: It has been set up an accelerated method of simulating to atmospheric corrosion by using wet/dry alternate test.The rust evolution rule of mass change vs time(in logarithmic coordinate) of low carbon steel under this test shows two linear sections with different slopes,in which the rust evolution transition in weight change corresponds to the compactness transition and crystallization transition during the rust layer growth.It has found that the rust evolution rule of low carbon steel in Wanning exposure site correlates to the rust evolution rule obtained by simulating the coastal atmospheric corrosion test,and the rust evolution rule of low carbon steel in Shenyang exposure site correlates to the rust evolution rule obtained by simulating the industrial acidic rain atmospheric corrosion test.These results proved the reliability of the simulated atmospheric corrosion accelerated test.

Key words: low carbon steel, atmospheric corrosion, simulated acceleration, rust evolution rule
