- This collaboration with University West, Sweden, is the first systematic study and full investigation of the rumpling of NiCoCrAlY coatings during cyclic oxidation. It shows how rumpling can be affected by experimental variables; it reveals one of the most important failure mechanisms of thermal barrier coatings used in hot sections of gas-turbine engines; it enables protection of superalloy components and improves engine efficiency. This work was adopted for development of next generation 2000 °C engine thermal / environmental barrier coatings for Rolls-Royce by Prof. Ping Xiao, appointed Rolls-Royce/Royal Academy of Engineering Research Chair in Advanced Coating Technology in 2019 (https://www.royce.ac.uk/rolls-royce-chair-in-advanced-coating-technology/).
