Several polymeric materials possessing widely different characteristics were investigated. Their scratch hardness was evaluated by a microscratch tester using Pelletier’s model, which allows calculation of the real contact area during the scratch process. The results were compared with relevant bulk mechanical properties and indentation hardness: scratch hardness correlated quite well with the latter and it was found to be strongly dependent on the compressive yield stress.

Abstract
Several polymeric materials possessing widely different characteristics were investigated. Their scratch hardness was evaluated by a microscratch tester using Pelletier’s model, which allows calculation of the real contact area during the scratch process. The results were compared with relevant bulk mechanical properties and indentation hardness: scratch hardness correlated quite well with the latter and it was found to be strongly dependent on the compressive yield stress.File in questo prodotto:
