Abstract

A process for increasing the lubrication of ductile-iron lubricated contacts includes abrasive-blasting and plasma etching a ductile-iron component prior to coating. A wear resistant or low friction coating is then formed on the iron substrate and the resulting coated component has greater lubrication than a corresponding non-blasted and non-coated component.
