Abstract: A method of treating a superalloy article, including selecting an article having a superalloy composition, whereby the article has a treatable feature on its surface. The method further includes removing a base alloy from a region abutting a first portion of the treatable feature. The method further includes treating a second portion of the treatable feature with a treatment composition to remove surface oxides. The method further includes inserting a treatment material into the first portion of the treatable feature followed by depositing the base alloy in the first portion of the treatable feature. The method further includes heat treating the article at a temperature above the melting point of the treatment material whereby the treatment material flows into the second portion of the treatable feature forming a treated article.

Abstract: A method of repairing an oxidized defect in a superalloy article includes removing substantially all of the oxidized defect to form a cleaned out portion of the superalloy article; filling a portion of the cleaned out portion with a weld by fusion welding; cracking the weld; and filling the cracked weld and a remaining portion of the cleaned out portion with a braze material.

Abstract: A method to repair an opening in a metallic device including: mount the device on a positioner; while the device is mounted on the positioner, sense and record positions of a surface of an opening in the device using a probe operated by a manipulator; based on the recorded positions determine a centerline and diameter of the opening; orient a digital model of the opening with respect to the opening of the device based on the centerline and diameter of the opening, and apply an weld or cladding to the opening by a welding torch maneuvered automatically by the manipulator while the device is mounted to the positioner and based on the oriented digital model of the opening.
