Abstract
Abstract The ability of engineering polymers to resist scratching action has rapidly become a vital requirement for diverse industrial applications because scratches may greatly reduce the life cycle of the components. Therefore, the present work aims to study the possibility of using roller burnishing process to enhance the scratch resistance of polymers to a single pass scratching action. The effects of burnishing feed rate and roller contact width on the scratch hardness of poly(oxymethylene) and polyurethane were considered. The results revealed that low burnishing feed rate and smaller roller contact width led to an increase in scratch hardness for both polymers. The scratch fractures were also observed using SEM to study the changes in wear modes.
