Friction characterisation of polymers abrasion (UHWMPE) during scratch tests: single and multi-asperity contact

Friction mechanisms and abrasion of the human finger pad in contact with rough surfaces

“…Nevertheless, the relationship between friction, abrasion and ploughing effects needs to be further investigated in future work. Experiments using a wider range of rough and abrasive materials as well as parameter studies on influencing factors would be useful for a more detailed understanding in combination with work on the applicability of theoretical concepts used in connection with the wear and abrasion of polymers [32][33][34]. New insights are also expected from extended analyses of the surface topographical modifications due to friction on the microscopic level, not only regarding the skin, but also the counter-surfaces.…”

Friction Analysis on Scratch Deformation Modes of Visco-Elastic-Plastic Materials

“…The groove is elastic if just after contacting there is no track visible, visco-elastic if the recovery of the deformed groove is delayed in time, plastic if a groove persists and visco-elasticplastic if a groove persists with partial recovery (Pelletier et al, 2008;Lafaye et al, 2008). Some results are presented in literature of scratch test experiments conducted on polymers, such as polycarbonate, polyethylene, PMMA (poly-methylmethacrylate), PTFE (poly-tetra-fluoro-ethylene), UHMWPE (ultra high molecular weight poly ethylene), PEEK (poly-ether-ether-ketone) (Briscoe, 1998;Ducret et al, 2003;Iqbal et al, 2011).…”

Effect of polysiloxane additives on the scratch resistance of an acrylic melamine automotive clearcoat

“…Modifying the viscoelastic properties of clearcoats aims to create plastic scratches. [7][8][9][10][11][12][13] Improving the scratch resistance of a clearcoat would require changes in its chemical structure, which is not easily achievable and may create other difficulties such as adverse effects on other properties and/or the price. Consequently, attempts to improve scratch resistance of a clearcoat by the incorporation of additives to restrict large variations in other properties of a clearcoat, as well as making it economically viable, provide an attractive alternative.…”
