Abstract

The corrosion inhibition effect of zinc metal in 1M Hydrochloric acid by 2-ethyl imidazole has been evaluated at room temperature using weight loss, gasometry methods. The corrosion inhibition efficiency increases with increase in concentration of an inhibitor. The corrosion rate decreases when increase in concentration of inhibitor. This is due to at the higher concentration of inhibitor solution which blocks the active site of a zinc metal and a protective film is formed over the zinc metal surface. This is further confirmed by surface analysis technique like scanning electron microscopy. Surface analysis of polished, corroded and inhibitor zinc metal surface has been evaluated by SEM.
