Corrosion Mechanisms and Cosmetic Corrosion Aspects of Zinc-Aluminium-Magnesium and Zinc-Chromium Alloy Coated Steel Strip

Abstract: behaviour of Zn-Al-Mg alloy coating (ZM/HDG) and Zn-Cr alloy coating (ZCE/EG) in comparison to conventional zinc coating (Z/HDG) are presented. The outstanding corrosion protection performance of the new zinc-alloy type coatings is based on the formation of special corrosion inhibiting layers. In the case of ZM/HDG the nature of the corrosion product layer is based on Hydrotalcite. Up to six fold corrosion protection was observed even with half of the coating thickness of ZCE/EG coatings and paint creepage is … Show more

“…Zn–Cr alloy coatings are of interest due to their better corrosion-protective properties than zinc coatings even at low thicknesses. The process of electrodeposition of Zn–Cr has been optimised over the years to enable high-speed deposition on steel strips for car body panels in the automotive industry [1,2].…”
