Electrochemical Investigation to Evaluate the Inhibition Effect of Schiff Base (Salpr) Against Magnesium Corrosion in Acidic Media

Magnesium and its alloys are increasingly used in aerospace and automotive applications owing to their ultra lightness (Their density is thirds that of aluminum and one fourth that of iron) and high strength to weight ratio [۱]. However, Mg is highly chemically reactive when exposed to air or water and forms oxide/hydroxide layer, which make it very susceptible to galvanic corrosion. The poor corrosion resistance of magnesium and its alloys restrict their wide application [۲-۳]. In this work, the inhibition effect of N,N-bis(salicylidene)-۲-hydroxy-۱,۳-propandiamine (Salpr) Schiff base on magnesium corrosion was studied using different electrochemical methods including; potentiodynamic polarization, Electrochemical Impedance Spectroscopy (EIS) and Electrochemical Noise (EN) methods.
