Test specimens of various aluminum alloys common to U.S. Department of Defense (DoD) systems or proposed for use in DoD systems were identically prepared and exposed under bare uncoated conditions in chamber based laboratory accelerated corrosion test methods to assess their relative susceptibilities to general corrosion attack. The methods used were ASTM B 117 neutral salt fog (NSF) and General Motors Standard 9540P (GM 9540P) cyclic accelerated corrosion. The NSF specimens were compared at intervals of 18, 72, and 168 hours. The GM 9540P specimens were assessed at 1, 5, and 10 cycle intervals. The corrosion assessments were graphically obtained using flatbed scanning techniques.
