Abstract

This work deals with synergistic corrosion inhibition efficiency of Azadirachta indica gum and
metal cations (Zn2+ and Ni2+) on mild steel in 1 mol L-1 HCl using gravimetric, potentiodynamic polarization
and electrochemical impedance spectroscopic methods. The effect of temperature (303 - 348± 1 K)
and immersion time (1, 2, 3, 4, 6 and 24 h) on the inhibition of corrosion has also been studied.
Corrosion kinetic parameters were calculated and discussed in detail. It obeys Langmuir adsorption
isotherm. The interaction of inhibitors with the mild steel surface has been established by Fourier
transform infrared spectroscopy.
