THE INFLUENCE OF FRICTION KINEMATIC PARAMETERS ON MICROHARDNESS OF SLIDINGS POLYMERS
Journal Title: Tribologia - Year 2011, Vol 239, Issue 5
Abstract
It is know that friction changes the microstructure of surface layer of the material. This modification follows as a result of interactions between contacting surfaces. There is a need to investigate the modification mechanism of the surface layer during friction. A subject of the investigation was the microhardness variation of some polymers after friction against steel. The experiment was done in surface-surface, sliding friction conditions. Vicker’s microhardness measuring method was used. The influence of some friction parameters (unite pressure p, sliding velocity vs, character of friction) on the microhardness of polymers is also described in the paper. The polymers used in the experiment were polyoksymethylene (POM), ultra high molecular weight polyethylene (PE-UHMW), polyamide (PA), and polytetrafluoroethylene (PTFE).
