This prospective study was designed to investigate the effect of sliding speed and load on the frictional characteristics of laser surface texturing of activated carbon composite derived from palm kernel. A dimple form was textured on the composite disc surface using laser surface texturing machine. The sliding test was conducted on both the textured and non-textured surfaces of the composite disc by using a ball-on-disc tribometer under lubricated conditions. Regardless of the surface topography, the friction coefficient increases with applied loads and decreases with increasing sliding speeds. However, the textured surface shows a lower friction coefficient as compared to the non-textured surface, particularly at higher sliding speed.
