Abstract

Corrosion inhibition effects of water-soluble peripheral substituted cobalt, copper and zinc metallophthalocyanines (CoPc(1), CuPc(2)and ZnPc(3)) on the copper metal in 0.1 N HCl were investigated by using gravimetric, electrochemical, SEM-EDS analysis and quantum chemical calculations. On the electrochemical investigations and gravimetric analysis the highest inhibitor efficiency was obtained with CoPc(1)at 1 x 10(-2)mol/L concentration. SEM-EDS results indicated parallel results and oxygen atom content increased in the order of ZnPc(3), CuPc(2)and CoPc(1). According to the quantum chemical calculations, following corrosion inhibition efficiency ranking was obtained: CoPc(1)> CuPc(2)> ZnPc(3).
