SBIR-STTR Award

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.

Technology Partners Inc. (TPI) proposes to advance two different material coating systems which met with success under the Phase 1. These coating systems are to be employed to combat corrosion over the temperature range from: 8000 C (14750 F) adjacent to the engine to 2000 C (4000 F) further along the exhaust system and will be engineered for maximum corrosion resistance and adhesion to steel. The primary objective of this Phase II program is the full scale application and demonstration of these high temperature coatings on actual pieces of Marine Corps equipment. The coating systems will 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. A materials and process versus performance database will be established for use during future development activities while adhesion and corrosion protection models will be developed.
