AbstractAdvanced gas turbine engine bearings will experience high DN (bearing speed in revolution per minutes times bearing bore in millimeter), increased load and high temperatures. State-of-the-art (SOA) materials such as Pyrowear 675, CSS-42L and silicon nitride are considered as potential bearing materials for advanced gas turbine engines. Surface modification of SOA materials is considered to enhance their relevant properties for such application. UES, Inc. proposes to develop surface modification technologies and coatings for the SOA materials. A systematic test methodology will be used to evaluate the relevant properties of the surface modified and coated SOA materials. Based on the evaluation results, the proposed surface modification technologies will be validated and ranked. Highly ranked technologies will be further developed in Phase II
