Abstract [en]

Aluminium is one of the prominent metals used in the automobile industries apart from cast-iron. Aluminium is used for lightweight material properties and, it meets some of the prominent mechanical properties. When aluminium is combined with silicon carbide, it improves some of the mechanical properties and provides similar strength as that of the cast-iron. The purpose of aluminium silicon carbide is to recover some of the mechanical properties and the thermal properties for the disc brakes. Aluminium is enhanced with 20% silicon carbide is cast using stir casting. In this paper, two different compositions are compared. The hardness of the samples was analyzed with the help of the Nano-indentation test. Alloy-1 shows better hardness values compared to Alloy-2. The scratch resistivity of the sample surfaces was analyzed under the microscope with the help of the Nano-scratch test. The presence of SiC particles in the aluminium matrix withstands the indenter to penetrate deep into the surface.
