Caffeine as a Green Corrosion Inhibitor for Carbon Steel in Corrosive Media

In this report, the corrosion inhibition of carbon steel in acidic media is done using caffeine as green inhibitor in hydrochloric acid. The inhibition efficiency of the green corrosion inhibitor was performed using weight loss measurement, Tafel plot and linear polarization resistance method. We...
