Abstract
A method of improving a superalloy component is proposed. The method involves the introduction of at least one additive into the superalloy component, the at least one additive being selected from the group of Hf, La, and Y. The at least one additive is introduced into a surface layer of the component. Preferably, the surface layer has a depth of 0.5 mm or less. The component may include, for example, an airfoil of a gas turbine.
