Abstract (en)
A coating for a component, such as a turbine aerofoil, which may provide said component with corrosion resistance and which may also provide enhanced resistance to fractures and crack propagation as well as low cycle fatigue resistance, is disclosed. The coating is a platinum aluminide comprising chromium, aluminium, platinum and silicon. The coating is formed of fine grains of the platinum aluminide and coarse grains of the platinum aluminide. The coating may provide an effective outermost coating on said component. A component comprising such a coating, a method of forming such a coating on a component and a cold spraying apparatus for applying such a coating are also disclosed. Furthermore the relative amounts of fine and coarse grains can be altered in different regions of the coating to provide chemical and/or mechanical properties which are tailored to the requirements in particular regions of a component.
