The loss of dimensional stability due to wear is a great challenge in the industrial environment. To cater to this need, the development of advanced materials is in a continuous process. The present work focuses on evaluating the mechanical and tribological properties of the newly developed Al composite reinforced with hard particle TiB2 and two solid lubricants, graphite and nano MoS2. Three different compositions of specimens with constant weight % of TiB2 and graphite are maintained to 10 %. A planetary ball mill is employed to reduce the micro MoS2 to nano level, and their weight % of nano MoS2 is maintained in varying levels of 10, 15, and 20 %. The liquid processing method of the stir casting technique is followed to fabricate the hybrid composite specimens. The microstructural study confirms the homogeneous distribution of the particles, whereas XRD analysis confirms the presence of particles. The pin and disc dry sliding wear test is conducted to examine the wear rate and CoF. The wear test outcomes declare that the increased inclusion of nano MoS2 reduces the wear loss and CoF. Post wear analysis through SEM micrographs confirms the presence of a lubricant layer that regulates the change in wear mechanism concerning the load. The remarkable low CoF of 0.11 is recorded for rich reinforcement with minimum load. 收起
