Abstract
Methods and apparatuses by which an oxidized metallic surface can be prepared for a subsequent repair operation without excessive removal of parent metal material. At least one gas is supplied to a limited portion of a metallic surface of a component, and the limited portion is locally heated in the presence of the gas to a treatment temperature sufficient to cause the gas or a gas that forms therefrom to chemically remove oxides from the limited portion of the metallic surface. At least a second portion of the metallic surface is not locally heated to the treatment temperature.
