Influence of Turkey Bone Particulate on Corrosion Resistance of Cast Aluminium Brass

This research investigates the effects of varying turkey bone particulate on the corrosion resistance of cast aluminum brass alloy. The study employed a systematic approach by preparing composite samples with turkey bone particulate contents of 0%, 1%, 2%, 3%, and 4% and subsequently performing comprehensive corrosion tests. Corrosion resistance was evaluated using an immersion method, in which the samples were immersed in 1.0 M, 1.5 M and 2.0 M of sulphuric acid and sodium hydroxide for a testing period of 195 hours. The samples were carefully observed and their mass loss were recorded every 3 hours. For the acidic medium, the mass loss of sample A (the control sample) is 0.7 g while that of sample D (with 3% turkey bone) is 0.4 g when immersed in 1.0 M of sulphuric acid. Other samples show more susceptibility to corrosion. For basic medium, samples A, B, C and D show higher values of mass loss when immersed in all the three concentrations of sodium hydroxide. Sample E (with 4% turkey bone) shows no mass loss when immersed in 1.5 M of sodium hydroxide. Therefore, addition of turkey bone particulate has a significant effect on sample E when immersed in 1.5 M of sodium hydroxide. The mass loss of sample A when immersed in 2.0 M of sodium hydroxide is 0.007 g while that of sample B is 0.002 g. Sample D shows highest corrosion resistance in sulphuric acid while sample E shows highest corrosion resistance in sodium hydroxide. Notably, the incorporation of 3 to 4 % of turkey bone particulate significantly influences the corrosion behaviour of the composite yielding an enhanced corrosion resistance. The study demonstrates that the incorporation of turkey bone particulate up to an optimal level can improve the corrosion resistance of cast aluminum brass, highlighting the potentials of turkey bone particulate (an agricultural waste) as a suitable and sustainable reinforcement material for aluminium composite..
