Corrosion Inhibition of Aluminium by Diethylene Triamine Pentamethylene Phosphonic Acid

A. Nithya, S. Rajendran

Abstract :

The inhibition efficiency (IE) of DTPMP in controlling corrosion of aluminium in an aqueous solution at pH3 in the presence and absence of Zn2+ has been evaluated by mass loss method. The formulation consisting of 200 ppm DTPMP and 10 ppm Zn2+ offers 98% inhibition efficiency to aluminium in an aqueous solution at pH3. A synergistic effect exists between DTPMP and Zn2+. Polarization study reveals that this formulation controls the anodic reaction predominantly. FTIR spectra reveal that the protective film consists a complex formed between the DTPMP– A13+
