Effect of Ce on Vitriol Corrosion Resistance of Aluminum Bronze Alloy Coatings

Abstract

The effect of Ce on vitriol corrosion resistance of aluminum bronze alloy coating was studied by static immersing corrosion test, electrochemistry test, XRD, SEM, EPMA, XPS et al. The results show that Ce can improve the corrosion resistance of Cu-14%Al-X coastings. Selective corrosion happened in 5%H2SO4 solution and Al and Fe were prior to be etched. This alloy coatings possesses good corrosion resistance.
