Methods for Creating a Zinc-Metal Oxide Layer in Metal Components for Corrosion Resistance

摘要

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.

主权项

1. A method for creating a metal object having a corrosion resistant layer, comprising:
incorporating zinc into at least a portion of at least one metal surface of a metal object that will be exposed during use of the metal object; forming a corrosion resistant layer within the portion of the at least one metal surface.
