摘要	The electrochemical features of the corrosion of AA2195-T8 aluminum alloy in 3.0% NaCl solution were studied by electrochemical noise(EN) technique, electrochemical impendence spectroscopy(EIS) and potentiodynamic scanning(PDS). At the initial stage, the pitting cores are formed. and the passive film is repaired continuously, which results in the inductive component in the electrochemical impendence spectrum. With prolonging the immersion time, the inductive component is disappeared gradually, and the impendence module is decreased largely. The passive region is very small, due to the little difference between pitting corrosion potential (E-pit) and self-corrosion potential (E-corr,). The polarization resistance (R-p) is increased and then decreased as the immersion time is prolonged, the self-corrosion current is changed in the form of reverse tend.
