Researchers at University West in Sweden are adding ceramic nanoparticles to the protective heat-shield layer in aircraft engines using suspension plasma spraying at 7000 to 8000 Celsius. The hope is that the porous thin layer (0.5 millimeters) could boost service life of the engines by up to 300 percent as well as making them more fuel efficient and so cheaper to run as well as less environmentally damaging. The research carried out by Nicholas Curry was conducted in close collaboration with aircraft engine manufacturer GKN Aerospace and Siemens Industrial Turbomachinery. It is likely to be used in both aircraft engines and gas turbines used in power generation within two years.
