Abstract
The rise in pollution is a serious matter of concern for all nations. Industries are mainly responsible for damaging the balance of the cycle of pollution. In this paper, the mechanical properties of Aluminum have been enhanced by reinforcing it with eggshell wastes and SiC as reinforcement particles. Ball-milling technique has been applied for up to 75 hours for making the densities of Aluminum, Eggshell and SiC equal. The prime focus of this work is to improve the hardness value of Aluminium-based final composite material. Friction Stir Process (FSP) technique has been used to develop the composite and the driving parameters of FSP like rotational speed, transverse speed etc. are optimized with the help of the Box-Behnken Design approach. The optimized value of rotation speed was 966.14 rpm as well as transverse speed was 23.18 mm/min. Hardness and tensile strength of composite developed at an optimum combination of parameters were found to be 72.2 BHN and 194.48 MPa respectively. Results showed that tensile strength and hardness were enhanced by about 44.05% and 64.09% respectively.
