摘要

Two kinds of anodic films (i.e., CAA films and BSAA films) on surfaces of 2060 Al-Li alloy weresuccessfully prepared by anodizing. The presenting work mainly focused on the contrastiveinvestigation about the effect of the two kinds of anodic films on corrosion resistance and fatigue crackinitiator. The morphologies of the samples were characterized by scanning electron microscopy(SEM), and the bonding strength between films and substrate was tested by WS-2005 automaticscratch tester. It was found experimentally that the two kinds of anodic films had nearly the samecorrosion resistance and bonding strength between the films and substrates. However, the CAA filmshad a greater influence on the fatigue crack initiator of 2060-T8 Al-Li alloy comparing to BSAA films.
