  • Methods for creating a zinc-metal oxide layer in metal components for corrosion resistance
    Patent number: 11136660
    Abstract: The present invention provides a method for manufacturing a finished metal object or product having a corrosion resistant layer integral to or within a top portion of at least one of its surfaces that would be exposed to a corrosive environment. In one embodiment, the method for manufacturing is directed to a finished metal tubing product having a corrosion resistant layer within its inside surface that is exposed to a fluid and wherein the corrosion resistant layer is a zinc-metal oxide layer, such as a zinc-chromium oxide layer, or a zinc-mixed metal oxide layer. In addition to methods of manufacturing, the present invention provides finished metal objects or products having a corrosion resistant layer integral to or within a top portion of at least one surfaces that would be exposed to a corrosive environment.
