Abstract
A metallic component, which may be an airfoil, includes at least one treated patch, wherein the entire thickness of the component within the treated patch is in a state of residual compressive stress. A surface-treated area overlaps at least a boundary between the treated patch and the remainder of the component. The surface of the component within the surface-treated area is in a state of residual compressive stress, so as to resist crack initiation at the boundary between the treated patch and the remainder of the component. A method is also provided for making such a component.
