• The effect of synthesised o-hydroxy acetophenone benzoyl hydrazone (HABH) on the corrosion of mild steel in 1M HCl was investigated using potentiodynamic polarisation (PDP), electrochemical impedance spectroscopy (EIS), thermogravimetric analysis, contact angle measurement and weight loss methods. The inhibition efficiency of HABH increases with surface roughness of emery paper up to 800 grits and thereafter it decreases with additional increase in surface roughness. TGA results also indicated that the inhibitor film on the surface had a relatively good thermal stability. The adsorption behaviour of HABH is experimentally investigated by contact angle measurement of acid solution on metal surface.
