Electrochemical Studies of Aluminium 7075 Alloy in Green Tea Leaf Powder as an Efficient Green Inhibitor

Abstract

Corrosion is a major issue in every industrial system. As a result of its widespread application, aluminum suffers enormous annual losses due to corrosion. Scientists are continually on the lookout for effective anti-corrosion strategies. Corrosion may be reduced in a number of ways, but many of them are harmful to the environment, so it's important to find a green alternative. Corrosion inhibitors in aluminum alloys can be found in green tea. In this research, we found that aluminum alloy 7075 (Al-7075) in a 3.5% NaCl solution was inhibited by both green tea. Samples of Al alloy are submerged in 3.5% NaCl solutions with and without an inhibitor for a total of 4 days. The weight-loss technique is used to determine the effectiveness of an inhibitor, with green tea with the best efficiency of 83.93% compared to the greatest efficiency of 14.29% for green tea.
