The proposed effort will advance the performance of refractory metals by integration of high temperature coating processes uniquely by means of modeling and experimental verifications in a focused, staged development. The ultimate goal of the proposed study will be to deliver the key enabling coating technology for at least a 400 degrees Celsius (°C) increase of the metal operating temperature from 1200°C to 1600°C.
This project will employ a new smart coating concept for refractory metal-borosilicide and -aluminide systems in order to provide a 400 °C increase in temperature resistance beyond that of current Ni-based superalloys in materials. Improvements 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 and resulting in lower operating costs.
