Abstract

Nowadays, the use of laminated composites is in huge demand in several industries due to the specific characteristics of the prepared material. Friction stir additive manufacturing (FSAM) method involves layer by layer addition where reinforcement particles can be embedded between the two layers to prepare laminated composites. This present investigation deals with the fabrication and micro-structural investigation of developed composite through friction stir additive manufacturing technique. TiC particles and grinding sludge, an industrial waste was used as reinforced material to develop AA6061/TiC/GS composite material. Optical microscopy, SEM analysis, EDS test and mechanical properties were investigated for the prepared composite. HSS tool having tapered pin tool was considered for the stirring action. Results revealed that no agglomeration of reinforcement particles was noticed for the fabricated material. An improvement in hardness and tensile strength was noticed for the prepared composite. The SEM analysis of FSAM tool before and after welding was also performed. Fractographic analysis was also performed for AA 6061/TiC/GS composite.
