Abstract

The friction and wear behaviour of the laser-textured surfaces sliding against a pin under the lubrication of the polyurea grease containing various additives were investigated using an UMT-2MT reciprocating friction tester. Results show that the dimple patterns have lower friction coefficients than that of the un-textured at lower sliding speed (0.015 m/s); however, the groove patterns have higher friction coefficients than that of the un-textured at all sliding speeds investigated in this article. Also, the anti-wear properties of the base polyurea grease and the base grease containing several additives on the textured and un-textured surfaces are discussed. Scanning electron microscopy and X-ray photoelectron spectroscopy were adopted to reveal the lubricating mechanism of different additives on the laser-textured surfaces.
