The corrosion laws of 2A12T4 aluminum alloy profiles in the harsh marine atmospheric environment
The corrosion behavior and electrochemical laws of 2A12T4 aluminum alloy profiles in harsh marine atmospheric environment were studied with the indoor simulation ex-periment of periodic immersion method.The experiment was conducted at drying temperature of 60℃and in the soaking solution of sodium chloride with wt 3.5%.The results show that significant pitting and heavy flaky erosion appear with the extension of time.The law of cor-rosion weight loss conforms to the power-law.The corrosion potential first decreases,then in-creases,then decreases,and finally stabilizes.
