Overlay/Bond Coatings that Resist Hot Corrosion in Navy Gas Turbines
SBIR Opportunity Analysis
The U.S. Navy, through the DoD SBIR program, is seeking solutions for overlay or bond coatings and an ICME-based predictive model to improve resistance to hot corrosion in marine gas turbines. The work centers on developing coatings that better protect turbine hardware from hot corrosion, oxidation, and stress corrosion cracking, especially in non-line-of-sight areas where poor coating quality has contributed to premature failures. Phase I emphasizes determining the corrosion mechanism at 500°-550°C, examining the roles of NaCl, Na2SO4, SOx, and stress, and validating the ICME framework with a short high-temperature test, while later phases expand to thermal barrier coating compatibility, commercial coating processes, and testing with engine OEMs. The solicitation is DON26BZ01-NV028, and applications are due June 3, 2026 at 4:00 p.m. UTC.
