Abstract:
1. A method of processing a component, the method comprising: providing a base metal having a feature, the base metal having a base metal composition, a base metal thermal expansion coefficient, a base metal yield strength, and a base metal elongation; removing the feature to form a processed region; applying a first layer to the processed region, the first layer having a first filler, the first filler having a first filler composition, a first filler thermal expansion coefficient, a first filler yield strength, and a first filler elongation; and applying a second layer to the first layer, the second layer having a second filler, the second filler having a second filler composition, a second filler thermal expansion coefficient, a second filler yield strength, and a second filler elongation; wherein the first filler thermal expansion coefficient is less than both the base metal thermal expansion coefficient and the second filler thermal expansion coefficient; wherein the first filler yield strength is greater than the base metal yield strength and less than the second filler yield strength; and wherein the first filler elongation is greater than the base metal elongation and less than the second filler elongation.
