Inhibitive Effect Of Ferrous Gluconate On The Electrochemical Corrosion Of Aluminium Alloy In H2SO4 Solution

Abstract

The Use Of Ferrous Gluconate As Corrosion Inhibitor On Aluminium Alloy In 0.5M H2SO4 Solution Was

Studied Using Gravimetric And Potentiodynamic Polarization Measurements. The Surface Morphology Of

The Aluminium Alloy Was Studied After Exposure To 0.5 M H2SO4 Solution In The Presence And Absence Of

Inhibitor Using High Resolution Scanning Electron Microscopy Equipped With Energy Dispersive

Spectroscopy (HRSEM EDS). The Adsorption Behaviour Of The Inhibitor Was Investigated. The Results Of

The Investigation Show That Increase In Concentration Of Ferrous Gluconate Corresponds To An Improvement

On Inhibition Efficiency. Equally, The Results Showed The Ferrous Gluconate To Be An Effective Corrosion

Inhibitor For The Aluminium In The Acidic Medium. The Results Obtained From The Two Methods Used Were

Found To Correlate With Each Other.
