Accelerated Corrosion Analysis of E-Coated Steel Box Panels to Determine Reapplication Intervals for Carwell Inhibitor

Abstract

Box Panel specimens of e-coated steel painted with Chemical Agent Resistant Coating (CARC) and treated with CARWELL commercial corrosion inhibitor were exposed to GM 9540P cyclic corrosion and to the vehicle accelerated corrosion test track at the Aberdeen Test Center at Aberdeen Proving Ground, MD. The box panels were chosen to simulate closed interior spaces found on typical military vehicles such as door panels on trucks. Panels with and without the CARWELL pretreatment were exposed for 100 cycles of GM 9540P. CARWELL treated panels were placed on the truck and monitored for crevice corrosion in the lap joint to determine the reapplication interval of the CARWELL treatment. No evaluation of the effectiveness and suitability of using CARWELL on exterior, unenclosed surfaces was performed.
