{011} planes which were medium close-packed planes were the dominating orientation in A sample (without burnishing) and B sample (a burnished sample) surfaces. There was not a common close-packed plane dominating orientation parallel to C sample (the other burnished sample) surface, and texture in this sample was abnormal. The corrosion property by electrochemical impedance spectroscopy was improved by burnishing process. Considering similar dislocation density obtained by XRD and grain boundary characteristic of two burnished samples, although the surface energy quantity for Al was (111). <. (001). <. (110), improved corrosion resistance was observed in burnished B sample. Moreover, the donor concentration of surface passive film was affected by burnishing condition and its effect on corrosion resistance was discussed. These results were further supported by SEM after corrosion immersion.
