The basic principles are described together with the new experimental approach for investigation of the scratch resistance that take into account the viscoelasticity and brittleness of polymer materials. The testing methods based on the wear particles with the measurements of changes in mass and/or volume are not enough reliable. The possibility of quantitative measure of wear is based on the method of multiple scratching of polymer material surfaces. Tribological properties are in correlation with the surface energy of materials. %K faktor trenja %K otpornost na brazdanje %K tribologija polimernih materijala %K tro enje / friction factor %K scratch resistance %K tribology of polymeric materials %K wear %U http://www.fsb.hr/polimeri/fileopen.php?id=918
