Abstract
Official abstract text for this publication.
A method of post processing a laser peened component to remove a laser remelt layer is proposed. The post processing includes a series of steps including grit blasting, chemical etching and mechanical finishing the component. This will ensure that the mechanical property (i.e., damage tolerance) benefit of laser peening is restored to the surface of the component.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a gas turbine component having an airfoil comprising: a) laser shock peening a base metal surface of the component; b) then grit blasting the surface; c) then chemically etching the surface after the grit blasting; and d) then mechanically finishing the surface after the chemical etching. 2. The method of claim 1 , wherein the component has sides, and a depth of a laser re-melt layer removed is less than 1 mil (0.0254 mm) per side. 3. The method of claim 1 , wherein the component is a vane. 4. The method of claim 1 , wherein the component is a blade.
