Abstract: A method of polishing an outer surface of a ceramic coated gas turbine engine component includes applying a rotating diamond brush to the outer surface. The brush is configured to achieve a uniform finish of 150 microinches RA or less over the surface. The brush contains diamond impregnated bristles, and is affixed to a rotary head of a robotic arm. A force sensing controller limits brush forces against the component. The component disclosed is a hot section turbine vane designed for directional control of high temperature, high-pressure combustion gases, but the method may be applied to other components utilized in similar aerospace applications. The polished coating provides an improved thermal barrier for maintaining structural integrity of the component in environments having temperatures ranging up to 2,000 degrees Celsius. The method limits abrasive removal of ceramic material to only 0.0005 to 0.00075 inch, and saves time and expense over past practices.

Abstract: A method of fabricating a finished part may comprise creating an unfinished part using a primary metal fabrication process, wherein the primary metal fabrication process leaves a surface deformation on the unfinished part, and removing the surface deformation from the unfinished part using a secondary metal fabrication process, wherein the secondary metal fabrication process further creates the finished part from the unfinished part. The disclosed method may save manufacturing steps and increase production accuracy.
