The effect of cashew juice extract on corrosion inhibition of mild steel in HCl

An evaluation of the effective performance of juices extracted from anacardium occidentale (cashew) on the corrosion inhibition of mild steel immersed in 0.1 M hydrochloric acid at ambient temperature was made. Weight-loss and potential measurement techniques were used for the experimental work. The juice extracts were obtained from the bark, nuts, and apples of the tree. The bark-juice extract provides no inhibition for the corrosion of the steel specimen, while the nut-juice extract accelerates the corrosion of the specimen under the conditions of the tests. However, the apple-juice extract at a concentration of 2ml/100ml of 0.1 M HCl gives good results of corrosion inhibition of more than average performance, as shown by the calculated inhibitor efficiency.
