Characterisation of abrasive worn surfaces by surface microtopography parameters

Abstract

Surface microtopography plays a dual role in the course of friction and wear processes. It affects the contact and temperature conditions, and it undergoes significant changes in accordance with the wear mechanism. The amplitude, spacing, hybrid and functional parameters of microtopographies provide opportunities for understanding more deeply the wear process. Wear experiments and surface roughness measurements before and after the wear were performed. The aim of this study was to define the availability of the roughness parameters to describe the microtopography modification during the abrasive tribological process.
