To avoid friction and wear at the interfaces of materials, an attempt has been made by adding solid lubricant MoS<sub>2</sub> to build such a self-lubricating composite with Al-matrix. The tribological analysis has been described based on the Taguchi orthogonal array (L27). Three variables combination such as sliding velocity, sliding distance and contact pressure are used for this study to determine the tribological responses, i.e. wear rate and coefficient of friction. The properties of composites were improved by increasing the weight % of MoS<sub>2</sub> and Al<sub>2</sub>O<sub>3</sub>. The tensile strength of Al-Si/2MoS<sub>2</sub>, Al-Si/12Al<sub>2</sub>O<sub>3</sub>, and Al-Si/12 Al<sub>2</sub>O<sub>3</sub>/2MoS<sub>2</sub> composites is 6.02%, 12.46%, and 2.44% compared to the base matrix. The addition of MoS<sub>2</sub> helps the hybrid composite to attain better tribological properties with a slightly lower specific strength. Analysis of variance showed that the composites such as Al-Si/2 MoS<sub>2</sub> and Al-Si/12Al<sub>2</sub>O<sub>3</sub>/2MoS<sub>2</sub> were strongly influenced by the pressure in wear rate. Similarly, sliding velocity affects the coefficient of friction for Al-Si/2MoS<sub>2</sub>. Wear tracks formed during the dry slide process were analysed using optical and SEM with an EDS. It was discovered that pressure plays a vital effect in the wear mechanism. The hybrid composite (Al-Si/12 Al<sub>2</sub>O<sub>3</sub>/2MoS<sub>2</sub>) material can be utilised in place of conventional materials in tribological demanding automotive applications</p>}, number={3}, journal={International Journal of Automotive and Mechanical Engineering}, author={VUDDAGIRI, HARI KIRAN and Vadapalli, Srinivas and Sagari, Jaikumar and R., Sivasankara Raju}, year={2021}, month={Sep.}, pages={8959–8977} }
