Published purpose

Thermal barrier coatings (TBCs) provide critical thermal protection to the superalloy metallic parts located in the hot sections of gas turbine engines permitting them to operate at higher temperatures. The power of a turbine is nearly directly proportional to its combustion temperature and advanced turbines are pushing the limits of operational temperature. The main objective of this partnership is to conceive, engineer and optimize the next generation of TBCs using thermal spray processes. The potential outcomes of this research project include new generation of thermally sprayed bond coats and suspension plasma sprayed (SPS) top coats with improved CMAS resistance and a comprehensive computer model to predict coating microstructure, roughness, porosity etc. These new TBC coatings will lead to production of more durable components and more energyefficient engines, lowering the maintenance costs and increasing flight safety. Consequently, these Canadian companies will be able to better compete in the global market
