Friction and Wear Characteristics of Coconut Shell Ash and Titanium Dioxide-Reinforced Al6061-Based Hybrid Composites
Aluminium 6061 matrix composites with reinforcement of titanium dioxide and coconut shell ash (CSA) were fabricated via the process of stir casting. The percentage of coconut shell ash was fixed at 3wt% and the Titanium dioxide was varied between 2 and 6wt%. The hybrid composites were microstructurally characterized and showed that, within the matrix the particles of both reinforcements were distributed uniformly. When CSA and TiO2 particles are added as reinforcements, then the hybrid composites' hardness increases monotonically. By employing a pin-on-disc tribo tester at the atmospheric circumstances, the tribological studies of dry sliding demonstrated that hybrid reinforcements improved the hybrid composites' wear characteristics and friction under various sliding speeds (0.314–1.57 m/s) and loads (20–80 N). The developed hybrid composites' wear rate and friction coefficient have been reduced by 42% and 35%, respectively, after incorporating coconut shell ash and TiO2 particles. The operating mechanism behind the hybrid composites wear behaviour and friction were studied by analysing samples after wear test utilizing scanning electron microscopy. Observations show that the governing wear mechanisms such as abrasion and delamination were found, and the worn pin surfaces of alloy exhibit a long and shallow crater, while hybrid composites showed least visible damage.
