Optimizing the Properties of AA 5052 Alloys through Silicon Carbide and Groundnut Shell Ash Reinforcements
Main Article Content
Abstract
This research focuses on three types of aluminium composites: AA 5052, AA5052 + SiC and AA 5052 + SiC + GSA. The composites were made by stir casting. The hardest of the hybrid composites was made from groundnut shell ash. The improvement was 75% as compared to pure AA 5052. The density was measured experimentally using the Archimedes technique and theoretically using the rules of mixture. Composition of hybrid composites were aluminum alloy 5052, aluminum alloy 5052/ silicon carbide (SiC) and aluminum alloy 5052/ SiC/ groundnut shell ash (GSA). Results were analyzed, including Material Removal Rate (MRR), Surface Roughness (SR) and Tool Wear (TW). The test results were analyzed and then optimized, using RSM. When calculating SR and MRR, feed rate was the most crucial factor. TW was shown to be most affected by tool speed, while MRR was least affected by the % wt. of reinforcement.
