Abstract

The effects of Schiff base-metallocomplexes on the corrosion of mild steel were investigated by corrosion weight loss measurements, electrochemical measurements and surface analyses in various aqueous solutions such as hydrochloric acid solution and pseudo cooling water. The maximum value of inhibition efficiency on the corrosion of mild steel in 1mol/dm3 hydrochloric acid solution was about 95.8% in the case of Indium (III) {N, N'-bis (salicylaldehyde)-1, 12-diaminododecane} complex. The molecules of Schiff base-metallocomplexes adsorbed on the surfaces of mild steels to depress the corrosion.
