Abstract

A process for chemically treating 6063 aluminum alloy photoreceptor substrate surfaces is disclosed. The process exposes 6063 aluminum alloy photoreceptor drum surfaces to aqueous caustic at high temperature. The resultant drum surfaces are etched and exhibit a dulled finish appearance. When the surfaces are contacted with drum roll spacer shoes, for example, as found in certain electrophotographic printing and copying machines, the spacer shoes experience greatly improved mechanical wear properties as measured by reduced weight loss of non-metallic drum to roll spacer shoes over many operating cycles. The chemical etching process affords greater wear resistance and extended life times to drum roll spacer shoe components.
