Abstract: 

To further reduce the spread of corrosive behavior within common metals used in aircraft and watercraft construction, understanding of cathodic and anodic reactions within crevices is needed. Additionally, the study of the effects of chromate-based paints on the electrochemical environment is conducted. This study was conducted in two halves, one considering anodic reactions of chlorine ions dissolved within water on aluminum samples. The other half concerned cathodic reactions of the aluminum ion within solution with aluminum samples. Cathodic trials were tested within a rotational environment. In both situations, measuring the current density and pitting potential allows for understanding of the advancement of corrosive behavior. The cathodic trials also take into account several variables including pH, aluminum ion concentration, and rotational speed. This study concludes corrosive behavior exhibited by both. Pitting is more clearly seen from the cathodic reactions where pitting is visualized. Further study to be conducted within chromate solutions with chromium ions on common building metals.
