Effect of aluminium spacer on galvanic corrosion between magnesium and mild steel using numerical model and SVET experiments

► Investigation of effect of spacer for different area ratios of AE44-mild steel. ► Change in anodic current density is different for different surface area ratios. ► Good agreement between numerical model estimates and SVET experimental results. ► Investigation of the effect of electrolyte depth on the galvanic corrosion.
