Abstract

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.
