A method for providing a wear-resistant component includes depositing an aluminum coating on a steel component to provide an aluminum-coated steel component, and subjecting the aluminum-coated steel component to a plasma electrolytic oxidation (PEO) process. The PEO process converts a surface portion of the aluminum coating to alumina. A wear-resistant component includes a steel component and a wear-resistant coating on the steel component. The wear-resistant coating includes an alumina surface portion and an underlying portion of either aluminum or aluminum and nickel combination or nickel aluminide that contacts the steel component.

Wear resistant component and process therefor

In one aspect, a spray foam chemical conversion coating includes a non-hexavalent chromium aqueous chemical conversion coating solution, a foaming agent, and a propellant. In another aspect, a method of producing a corrosion-resistant coating includes spraying a foam chemical conversion coating on a surface of a metal substrate, allowing the foam chemical conversion coating to react with the surface, and removing excess foam chemical conversion coating from the surface. The foam chemical conversion coating contains no hexavalent chromium.

Application of type II chemical conversion coatings (CCCS) using foaming agents

A handheld applicator for delivery of post-treatment coating following application of a conversion coating includes a first vessel extending longitudinally and containing SOCOSURF PACS™ solution, a second vessel extending longitudinally and containing hydrogen peroxide, a pH indicator contained in one of the first or second vessels, a mixing region configured to combine the SOCOSURF PACS™ solution, hydrogen peroxide, and pH indicator.
