Abstract
An alloy component having an oxide film formed on its surface. The oxide film has atoms of a metal incorporated therein by a process comprising immersing the alloy surface in high-temperature water in which compound containing the metal is dissolved. The metal has the property of increasing the corrosion resistance of the alloy when incorporated in the oxide film. The compound has the property that it decomposes in the high-temperature water to release atoms of the metal which incorporate in the oxide film.
