The stabilizing temperature and time of the ZA35-0. 3Sr alloy were presented by electrochemical measurement of Tafel polarization curves

impedance spectroscopy test and microstructure analysis. The results show that the ε phase disappears due to dissolution into the matrix

and the non-equilibrium β phase at grain boundaries are eliminated after suitable stabilizing treatment for ZA35-0. 3% Sr alloy. The corrosion current density is reduced by 75. 69% and the corrosion resistance of the alloy is enhanced obviously compared with those of the alloy without treatment. The ZA35-0. 3Sr alloy with excellent corrosion resistance after stabilizing treatment is attributed to the increase of charge transfer reaction resistance and decrease significant of electrode electric double layer capacitor. The proper stabilizing treatment is at 350 ℃ for 4 h.
