Abstract

This research investigated the effect of surface modification on a soft curvature cup made of acrylonitrile butadiene styrene (ABS) against hard metal ball bearing. The experiment was conducted using different ABS surfaces (flattened and embedded with pits). Different pits embedded on the curvature cup have shown the potential for improving the tribology of hard-on-soft (HoS) sliding contact. The data included the evaluation of anti-wear and anti-friction properties for the lubrication with palm oil. A modified four-ball machine as a hard-on-soft screening machine has been used to evaluate the friction on ABS sample. The results showed that undertreated curvature cup with pits and lubricated by palm oil had a better frictional rate and allowed for a stable of hard-on-soft sliding
contact.
