Upgrading Corrosion Control Technologies During System RESET

During their service life legacy ground weapon systems can suffer from corrosion deterioration either due to a lack of, damage to or depletion of corrosion control systems installed during original manufacturing.  As these systems are being refurbished in RESET programs there is the opportunity to restore or upgrade the corrosion control systems of these assets.  During the repair of these vehicles the systems are largely disassembled, cleaned to bare metal and repainted / reassembled to like-new condition.  With such major disassembly already occurring improved coatings and corrosion resistant parts can be readily incorporated into the system during this repair.  This will result in a system that has an extended service life as compared to one where repair only incorporates the use of the Chemical Agent Resistant Coating (CARC) paint systems.  This paper presents the in-progress work of an OSD project to evaluate the effectiveness of utilizing zinc-rich coatings, metalizing, chip resistant polyurethane coatings and other corrosion control technologies on US Army and Marine Corps ground weapon systems.
