Effect of Heat Treatment on the Corrosion Behaviour of Nickel Surface-Deposited Agro-Reinforced Metal Matrix Composites

In the perspective of world’s apprehension with the environment, the current work proposes to determine an alternative way for disposing bamboo leaf ash (BLA) residual debris. The widespread utilization of bamboo results in widespread accumulation of bamboo leaf residual wastes, and the unchecked burning of the residual debris for the disposal of bamboo leaf stages a grave threat for both human and environment. The higher reserves of siliceous and aluminous materials in bamboo leaf ash can be used as effective filler material during the fabrication of several eco-friendly, low-cost, low-weight, amply available composite material systems. The current research chiefly aspires for inspecting the heat treatment characteristics of nickel-deposited aluminium-reinforced bamboo leaf ash composites. Al-BLA composites are fabricated by engaging a classic stir casting practice varying the reinforcement compositions, i.e. wt.% 2, 4, 6. The fabricated Al-BLA composites are nickel plated by employing a customary stirred watts bath. Potentiodynamic polarization tests have been executed for assessing the corrosion behavioural traits of the composites preceding and succeeding the T6 heat treatment in aerated 3.5% NaCl ambience. Microstructural and surface morphologies are determined by engaging XRD and SEM techniques. © 2021, The Institution of Engineers (India).
