High mach gas turbine engines will require bearings to operate at high temperatures (900-1200ºF). At such temperatures fluid lubricants will not work. UES Inc. proposes to develop robust high temperature solid lubricant coating systems utilizing commercially viable process. The coating systems will be characterized in terms of adhesion, microstructure, mechanical properties and tribological characteristics in relevant temperature regime. Based on their performance ranking, coating systems will be identified for further development in Phase II. BENEFIT: Successful completion of the project will enable the operation of bearings at higher temperatures for military (high mach gas turbine engines) and commercial (hot profile rolling, power generation etc.) applications.
