ABSTRACT:
The process of forming a composite with an alloy having an alloy component of about 0.5 to 12% aluminum and a matrix selected from a material of the group consisting of copper, iron or nickel. The alloy is heated in an oxygen-rich atmosphere to form a material oxide-rich layer on a surface of the alloy. The alloy is then heated in a reducing atmosphere to reduce the material oxide-rich layer to form an aluminum oxide on the surface of the alloy and a material-rich layer on the aluminum oxide layer.
