  • Patent number: 11925922
    Abstract: The present invention relates to a method of improving the corrosion resistance of a metal substrate surface using an oxygen reduction catalyst, which may improve the corrosion resistance of the metal substrate surface by coating the metal substrate surface with the oxygen reduction catalyst so that the metal substrate surface is changed to a passive state through the action of the oxygen reduction catalyst in an environment in which a stable oxide layer is not spontaneously formed on the metal substrate surface. The present invention has an advantage in that it can dramatically improve the corrosion resistance of the metal substrate under a corrosive environment by allowing a recoverable oxide layer to be formed on the metal substrate surface through the action of the oxygen reduction catalyst, applied to the surface, even in an environment in which an oxide layer is not spontaneously formed on the metal substrate.
