Cold spray’s hot potential in repairing aircraft
A new method of spraying metallic powders on the surface of worn-out aircraft components at relatively low temperatures holds promise for the aerospace industry.
While engine components in aircraft need to be built tough, these parts must be able to withstand soaring temperatures of around 650°C, and also contend with mechanical forces that can lead to wear and tear over time. But regularly scrapping and replacing gas turbine components is an expensive and laborious process, especially when replacement parts are not readily available.
A*STAR researchers led a study on the performance of CS relative to the current gold standard, APS. “As Inconel 718 powders can be deposited by both techniques, this study can help the research community and industry players compare them directly.”, said Jinsheng Pan from A*STAR's IMRE.
The A*STAR-affiliated researchers contributing to this research are the Institute of High Performance Computing (IHPC), Institute of Materials Research and Engineering (IMRE) and Institute of Manufacturing Technology (SIMTech).
