Abstract

The corrosion inhibition of 304 stainless steel in 1.0 M H2SO4 has been investigated in the presence of Henna leaves (Lawsonia Inermis) extract using weight loss measurement and Scanning Electron Microscope (SEM) analysis. The study indicates that the corrosion inhibition efficiency increases with the increase in concentration of Henna leaves extract and decreases with increase in temperature. SEM analysis indicated the changes in metal surface morphology in the presence of inhibitor. The result obtained indicated that Henna leaves extract act as an efficient green corrosion inhibitor for 304 Stainless Steel.
