Niranjan Hugar, Venkata Narayana B, Sunil Waddar, Manjunath K, Mohan Kumar K, Santosh N, 2024. TiO2 Particles Influence on the Wear Conduct of an Aluminium AA6061/Red Mud Hybrid Composite, ESP Journal of Engineering & Technology Advancements  4(1): 17-31.


The current study was carried out with the new goal of developing and characterising high-performance hybrid Aluminium AA 6061/Red Mud composites with varied wt.% TiO2 (0, 2, and 4% wt.%) for tribological applications. In this regard, ultrasonic-assisted stir casting is used to create composites of various compositions and machine them to ASTM G99-95a standards. The pin-on-disc wear test is performed on a Ducom TR-12 tribometer in accordance with the L27 Orthogonal Array (OA) for varying load parameters of 10 N, 20 N, and 30 N, sliding distances of 500 m, 1500 m, and 2500 m, and disc rotation speeds of 200 RPM, 400 RPM, and 600 RPM, while the hardness test is performed on a Brinell Hardness tester. The results show that the Specific Wear Rate (SWR) and Coefficient of Friction (COF) decrease as the wt.% of TiO2 increases, although the hardness values rise for the same wt.% of reinforcements. Response Surface Methodology is used to validate the results further (RSM). The hall petch strengthening process is mostly responsible for the increase in hardness and wear resistance.
