Project Description

This project is a university-industry partnership which will provide contributions both in the fundamental mechanisms of coating materials degradation as well as on the practical production of materials. The work will involve the development of a TBC/EBC coating system and investigation of the degradation of the coating system. The focus of the proposed project is on the interlayer between the alloy and ceramics TBC and the hot corrosion behavior of prospective pyrochlore materials. In particular, the interaction of the outer pyrochlore layer with a CMAS deposit and different gas atmospheres will be evaluated.

Project Benefits

This project will develop reduced cost bond layers for multi-layer thermal/environmental barrier coatings. Improvement to high-temperature advanced-materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to improvements in efficiency and operational flexibility, resulting in lower capital and operating costs.
