Project Description

This project will fabricated novel double-layer functionally graded TBCs will be using High Velocity Oxy-Fuel thermal spray (HVOF) and/or Air Plasma Spraying technology. The TBC materials will be characterized, their corrosion resistances at elevated temperature and corrosive environments will be evaluated, and their performance under corrosive environments at high temperatures will be measured. Additionally, parameters that affect residual stresses in TBC laminates, such as composition and thickness of layers will be identified. Laminated materials with the desired bulk residual stresses will be designed and their failure mechanisms and mechanical performances will be studied. Finally, a computational model to predict residual stress in the TBCs will be developed.

Project Benefits

This project will develop novel functional-gradient thermal barrier coatings in coal-fired power plant turbines. The development of lower thermal conductivity and better thermal stability is crucial to high temperature applications such as in coal-fired power plant turbines. 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 operating costs.
