摘要：
The electrochemical corrosion behavior of 7003 aluminum alloy (AA7003) under peak aging (PA), double peak aging (DPA), and regression re-aging (RRA) in sodium chloride (NaCl) solution at different temperatures have been studied by using potentiodynamic polarization and electrochemical impedance spectroscopy tests in combination with scanning electron microscopy. The results showed that the electrochemical corrosion rate of AA7003 in 3.5 wt% NaCl solution increases with increasing temperature, and the effect of aging treatments on the electrochemical corrosion rate in descending order is as follows: PA>DPA>RRA.
