Abstract:The tribological behavior of friction materials is complex under various operating conditions. The present article discusses the sensitivity of tribological behaviors of friction materials to load and speed under dry and water-lubricated conditions qualitatively and of values was also analyzed quantitatively based on regression analysis. The friction and wear behaviors of friction materials were evaluated on a ring-on-block-type test rig. It was observed that the material itself was the dominant factor in sensitivity of friction materials, followed by sliding speed. The influence of the interaction of load and speed was negligible under water-lubricated condition. The friction coefficient of the composite was less sensitive to operating parameters under water-lubricated condition.
