Production and Tribological Characterization of Stir-Cast Hybrid Composite Aluminium 6061 Reinforced with Sic and Ti Particulates

Abstract

The Aluminium 6061 alloys are mainly used in the application of automobile and aeronautical applications. An attempt has been made to increase the mechanical and tribological property of Al6061 alloy by adding SiC and Ti particulates as reinforcements. The ratio of particulates based on weight percentage such as (2.5%, 5%, 7.5%, and 10%) both SiC and Ti. The composite is developed by stir casting method. The particle size of SiC and Ti between 16 to 22μm. The optical microscopic test is conducted to examine the distribution of reinforcement particulates. Rockwell hardness test and XRD test also included calculating the hardness and constituents present in the composite samples. Friction and wear test is done by pin-on-disc method and the microscopic examination done by scanning electron microscope (SEM).The investigation results that Al6061 hybrid composite with good tribological properties and used in automobile components for reliable, long life and high performance.
