Abstract

The paper shows the evaluation of delamination of HDG coating. The HDG coating adhesion was evaluated by impact test and by pull-off test. The effect of substrate steel chemical composition, metallurgical conditions and other parameters influencing the quality of zinc coating, mainly the intermetallic phases, are described. The silicon content in aluminium-killed steel was identified as crucial factor for tested samples. The result of adhesion test corresponds to structure of zinc coating.

Keywords: HDG coating, adhesion, steel chemical composition, intermetallic phases
