Rolls-Royce has blades covered
Rolls-Royce has acquired exclusive rights to use a coating invented by Iowa State University researchers that helps turbines stand up to the heat in jet engines.
The bond coating will be applied to engine turbine blades made of nickel-based superalloys. Those superalloys are designed for strength but need help withstanding metal temperatures approaching 2,100 degrees Fahrenheit inside the hot section of a jet engine, said Brian Gleeson,
The bond coating is said to improve the durability and reliability of a ceramic thermal barrier that is applied over the bond coat, said Daniel Sordelet, a senior scientist and group leader for the US Department of Energy’s Ames Laboratory on the
‘This coating composition is very good in terms of performance,’ Gleeson said. ‘It offers significant advantages over existing coating technologies.’
