Langues : Anglais (eng) Index. décimale : 668.9 Polymères Résumé : The increasing utilization of polymers in sliding members has triggered much research on the enhancement of surface quality and tribological performance. In this regard, no work has considered the application of roller burnishing as a new surface treatment method for polymeric surfaces. The present work aims to investigate the influence of burnishing feed and roller contact width on the sliding friction and wear performance of acetal homopolymer and polyurethane. Dry and lubricated sliding conditions for both parallel and crossed burnished orientations were considered. The results revealed that low burnishing feed rate and smaller roller contact width led to a decrease in coefficient of friction for both polymers while improvement in the wear resistance was observed. Hence, it can be suggested that the roller burnishing process has high potential as a valuable polymer surface treatment technique.

Improvement in the scratch resistance of polymers by roller burnishing process / K. O. Low in INTERNATIONAL POLYMER PROCESSING, Vol. XXV, N° 3 (07/2010)  

[article]  inINTERNATIONAL POLYMER PROCESSING > Vol. XXV, N° 3 (07/2010) . - p. 176-180 Titre : Improvement in the scratch resistance of polymers by roller burnishing process Type de document : texte imprimé Auteurs : K. O. Low, Auteur ; N. S. M. El-Tayeb, Auteur ; P. V. Brevern, Auteur Année de publication : 2010 Article en page(s) : p. 176-180 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Microscopie électronique à balayage Polissage Polyoxyméthylène Polyuréthanes Résistance à l'abrasion Index. décimale : 668.9 Polymères Résumé : 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.
