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.
