Abstract: A process of remanufacturing a component such as an attachment flange used in turbochargers is provided and includes using a steam oxidation process to form an adhesion layer on top of a sealing surface of the component. The adhesion layer is an oxidation layer that a thermal metal spray coating can be applied on top of in order to prevent spalling that can occur at high heat. Once the process is completed, the component can be inspected to ensure that it meets or exceeds the manufacturer's original specifications.
