An insight into the effect surface morphology, processing, and lubricating conditions on tribological properties of Ti6Al4V and UHMWPE pairs

The effects of surface topography, processing, and environment conditions during tribological contact between Ti6Al4V titanium alloy UHMWPE friction pairs were systematically evaluated. Hence, in this research the polyethylene samples (blocks) having a constant roughness rubbed against counter-bodies (rollers) made with different surfaces. counter-samples manufactured using either dry machining and/or minimum quantity lubrication (MQL) conditions. Such cutting are harmless to humans environment. Simulated body fluid (SBF) distilled water was used simulate trials. We have noted that lubricant applied protect integrity machined parts, rollers, only minor impact on features tested. Further, produced demonstrated slightly lower momentary coefficient temperature. In contrast, MQL method enable reduced significant wear accumulation. it found maximum values Sa texture parameter associated parameters do not exceed 21% 4%, when is methods, respectively. Nevertheless, revealed much better resistance comparing SBF, later one trigger as well an accentuated progress patterns. results study important design new biomedical components by finish turning. • Effects surface, process behavior - pair. studied simulated (SBF). presence surfaces compared SBF presence. some typical mechanisms such abrasion, adhesion ploughing.
