Abstract

The zinc coating and/or zinc alloyed coating is one the most frequently used type of corrosion protection. This study was carried out to investigate and evaluate the corrosion behaviour of aluminium zinc alloy coated steel sheet at atmospheric condition. The aluminium-zinc hot dip coating was exposed for 10 years at industrial atmospheric test site Kopisty, Norther Bohemia. The article gives the overall evaluation of long-term exposed coating and progress of degradation of coating on cut-edges.

Keywords: Zinc alloyed coating, 55%Al-Zn, atmospheric test, coating morphology, corrosion
