Abstract

The corrosion products formed on Zn, Zn-55Al and Al-8.2Mg-4.8Si alloys coating has been investigated by potentiodynamic polarization in a mixture of 0.5 M Na₂SO₄ and 0.1 M NaCl solution. The anodic current density on Zn and Zn-55Al alloys coating show the existence of dissolution indicated that Zn and Zn-55Al alloy continued to dissolve across the corrosion product formed. The existence of corrosion product on Al-8.2Mg-4.8Si alloys coating shifted the polarization curves to more noble direction and inhibit the dissolution.
