Corrosion-Deformation Interactions (CDI)of AA2024-T3 in Chloride Media

Article Preview

Abstract:

Effects of CDI on corrosion behavior of AA2024-T3 in 3% NaCl aqueous solution are investigated through electrochemical techniques. the results show that CDI could lead to negative shift of free potential, breakdown potential and protection potential of AA2024-T3 and enhance the sensitivity of AA2024-T3 to pitting. The electrochemical impedance spectrum results show that Rp decreased significantly under applied stress and Rp can be taken as the indicator to evaluate the effect of CDI. Different strain rate could influence the effect of CDI on corrosion behavior and effect of CDI exhibit more significantly under low strain rate.
