Zusammenfassung

Korrosionsmechanismen und Eigenschaften bezüglich kosmetischer Korrosion von Zn-Al-Mg (ZM/HDG) und Zn-Cr (ZCE/EG) Legierungsüberzügen werden im Vergleich zu konventionellen feuerverzinkten Stahlband (Z/HDG) dargestellt. Die verbesserte Korrosionsschutzleistung der neuen Legierungsüberzüge basiert auf der Bildung spezieller korrosionsinhibierender Schichten. Im Falle von ZM/HDG enthält diese Hydrotalzit. Besonders die Verbesserung der kosmetischen Korrosion (z. B. Lackunterwanderung) ist ein wesentlicher Produktvorteil dieser neuen Beschichtungen.

Summary

Corrosion mechanisms and cosmetic corrosion 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 reduced down to 50 % in comparison to conventional zinc coatings (Z/HDG, ZE/EG). This clear improvement in corrosion protection is surely one of the most important product properties.
