Overlay/Bond Coatings that Resist Hot Corrosion in Navy Gas Turbines
SBIR Opportunity Analysis
The Department of the Navy is seeking an SBIR solution to develop overlay or bond coatings and an integrated computational materials engineering model that can resist hot corrosion, oxidation, and stress corrosion cracking in marine gas turbines. The work centers on understanding corrosion mechanisms in the 500°-550°C range, correlating the effects of salts, sulfur compounds, and stress, and producing coatings and predictive tools that extend service life in naval propulsion systems. Phase I calls for a short-term high-temperature feasibility test and initial ICME model development, while later phases expand to thermal barrier coating compatibility, commercial coating processes, burner-rig or similar testing, and eventual engine-component demonstration. The opportunity is open under solicitation DON26BZ01-NV028 / 26.BZ, with applications due by 2026-06-03 at 16:00 UTC.
