Corrosion process depends on: • Chemical processes of amalgamation of aluminium with mercury. • Diffusion process of aluminium in amalgam. • Electrochemical oxidation of aluminium on amalgamated Interface/water. The diffusion step appears different from that usually found in studies of aqueous corrosion and was not dependent on rotation of electrode but on diffusion of dissolved aluminium in the amalgam before the electrochemical oxidation of amalgamated metal. This is the limiting step of the process at stationary phase of the chemical amalgamation. This occurs at contact time mercury-aluminium longer than 36 min .For shorter times less than 30 min, chemical amalgamation controlled the process. Characteristic parameters of electrochemical behaviour of amalgamated electrodes were investigated: time of cathodic deposit of mercury, time of immersion of electrode in electrolyte before polarisation as well as potential scanning rate.
