AN ESTIMATION OF THE INFLUENCE OF THE SUBSTRATE PREPARATION ON TRIBOLOGICAL PROPERTIES OF NANOCERAMIC OXIDE LAYERS
Journal Title: Tribologia - Year 2014, Vol 256, Issue 4
Abstract
The article presents the results of tribological measurements of an aluminium oxide layer, obtained on aluminium alloy substrate with different degrees of surface preparation, with a plastic material in sliding cooperation. The utilitarian goal of the research was to reduce an unfavourable influence of oxide layer surface roughness during the abrasive wear process of the plastic material with the layer. The purpose was achieved by determining the effect of surface preparation on the formation of the surface topography and tribological properties of oxide layer of nanoceramics. The testing pin–plane was conducted on friction– wear conditions. The analysis of the tribological results was supplemented by surface morphology studies and stereometric research made before and after the tribological test. The results showed a significant effect of surface preparation on the formation of surface topography and tribological properties of the surface coating.
