| Abstract: | The fatigue corrosion behavour of 2024T3 aluminum alloy test pieces is studied in the acidic sodium chloride solution of 45℃ and pH=3.8 under 4 surface protective coatings. The experimental results show that the fatigue corrosion behavour of the alloy test pieces being anodized in chromic acid is better than that in sulfuric acid, and to coat a H062 zincbearing coating on the two kinds of anodized 2024T3 aluminum alloy test pieces can greatly improve their fatigue corrosion behavour. According to the quantitative analysis of the experimental results, the fatigue corrosion life expressions of the four kinds of surface protective coating aluminum alloy test pieces are obtained at the loading frequency 1.25Hz in the acidic sodium chloride solution of 45℃ and pH=3.8. |
