ABSTRACT:
An alloy, e.g. an aluminum/silicon or aluminum/copper alloy, incorporating an anodizable and non-anodizable phase is selectively etched to remove the non-anodizable phase from the surface. The surface is then anodized to provide a continuous oxide film, e.g. to impart wear resistant properties to the surface.
