High Temperature Coated Low Inertia Turbocharger Turbine Wheels (TurboCoat) researches coatings for use onturbocharger components as an enabler technology for the use of new advanced base materials. The projectwill focus on the turbine wheel which today is manufactured from Inconel, a very expensive nickel alloy. Newbase materials are being developed by the turbocharger industry, for reduced cost and lower inertia, howeveras exhaust temperatures for petrol engines are increasing beyond 1000 Deg. C. these materials will requiresurface coatings to be durable in this extreme environment. This project will research potential new coatings,application techniques and surface treatments that will enable these new materials to withstand the harshenvironment of a turbocharger. Small scale sample tests will be run to establish which combinations of coatingsand base materials perform the best and are worthy of taking through to full validation testing.
