High Temperature Corrosion Resistant Coatings for Military Vehicle Exhaust Systems

Technology Partners, Inc. (TPI) proposes three different material coating systems to be employed to combat corrosion over the temperature range from 800 degrees Celsius adjacent to the engine to 200 degrees celsius further along the exhaust system. These coating systems will be engineered for maximum corrosion resistance and adhesion to steel. They will also be formulated for application using conventional porcelain enameling equipment, thus reducing commercialization and scale-up time considerably. These application techniques are commonly used, well understood and extremely cost-effective. In addition to providing high temperature corrosion resistance, the microstructure of the coatings will be controlled to provide good thermal and mechanical shock resistance.
