Abstract:

This report is the second of three and summarizes the program of the Chemistry Research Division to formulate an inhibitor for high strength aluminum alloys against environment assisted cracking. Presented are the effects on the electrochemical and fatigue properties by various acid rain analogs, surface pretreatment, wetting agents, and different inhibitor formulas. The program was able to produce 6 candidate formulas for use against environment assisted cracking, and 12 formulas for use as general corrosion inhibitors.
