Abstract:

This report contains details summaries of investigations related to corrosion and degradation of coated metals, with applications to Army and other DoD service problems. There are projects on the connection of performance in accelerated test conditions to field exposures with a focus on parameters such as ozone and UV that have not received much attention. Many projects describe new, innovative, and sensitive approaches for assessing the degradation of coated metals including direct optical interrogation, AFM scratching, scanning Kelvin Probe, Raman spectroscopy, different IR spectroscopies, and combinations of these techniques. Also included is a study of the degradation of uncoated copper and the influence of parameters such as chloride deposition rate. These topics have also been captured in peer reviewed papers and thesis dissertations, so is being disseminated widely.
