With measuring and analyzing corrosion morphology,potential and EIS,the initial corrosion of aluminum alloys in marine atmosphere and correlation of simulated marine atmosphere accelerated corrosion test and outfield corrosion test were studied.

Usually,corrosion resistance of weathering steels is evaluated by the weight-loss method in an accelerated corrosion test.

The corrosion behavior of typical high-strength aluminum alloy LC4 was studied by accelerated corrosion tests of cyclic wet-dry intermittent immersion designed to simulated industrially polluted atmospheric environment,and corrosion mechanism was also discussed.

Using electrochemistry experiment,salt spray tests and accelerated corrosion experiment,under the ocean atmospheric corrosion and the polluted air corrosion environment,the corrosion behavior of different composition of hot-dip Zn-Mg alloy coated steel sheet was studied.

After having been corroded by seawater in accelerated corrosion experiment, based on rule and cause of changes of strength and weight loss rate, experiment data has been provided for quantitative analysis of broken state.

After having been corroded by seawater in accelerated corrosion experiment,basing on rule and cause of changes of strength and weight loss rate,experimental data has been provided for quantitative analysis of broken state.

Based on the research of accelerated corroded test and understanding for diffusion regularity,the distribution function of the concentration of mass rock and concrete materials is obtained in consideration of chemical reaction effect.

5 and subjected to different hydrochloric acid attacks were investigated by means of the accelerated corroded test.
