Abstract

A method for increasing oxidation resistance of an alloy surface comprises scanning a high energy source onto the alloy surface to melt the alloy surface; after the melted alloy surface solidifies, re-melting at least a partial area of the alloy surface using the high energy source to thereby form a re-melt layer, such that the alloy surface comprises a first oxidation resistance, the re-melt layer comprises a second oxidation resistance, and the second oxidation resistance is greater than the first oxidation resistance.
