Abstract

A series of experiments was carried out using a rolling-type tribometer to investigate the effects on friction behavior of the average velocity of the lubricant at the inlet to the contact zone (V) and sliding velocity (ΔV) during deformation. Experiments with pure aluminum strips of two different surface roughnesses showed that the variations in the friction coefficient with V and ΔV are largely dependent on the initial surface texture of the workpiece. For a smooth workpiece, the friction coefficient decreases with increasing V or decreasing ΔV. However, for a rough workpiece, the friction coefficient initially increases and then decreases with increasing V or ΔV. Observations of the rolled surface for a smooth workpiece shows that, with increasing V, the slip band becomes more marked, and with increasing ΔV, the rubbed portions become more severe. For a rough workpiece, no clear difference in rolled surface textures can be recognized due to the variations of V and ΔV.
