TY - JOUR N2 - The paper presents the results of investigations of the growth of protective coating on the surface of ductile iron casting during the hot-dip galvanizing treatment. Ductile iron of the EN-GJS-600-3 grade was melted and two moulds made by different technologies were poured to obtain castings with different surface roughness parameters. After the determination of surface roughness, the hot-dip galvanizing treatment was carried out. Based on the results of investigations, the effect of casting surface roughness on the kinetics of the zinc coating growth was evaluated. It was found that surface roughness exerts an important effect on the thickness of produced zinc coating L1 - http://journals.pan.pl/Content/88994/PDF/04_paper.pdf L2 - http://journals.pan.pl/Content/88994 PY - 2016 IS - No 1 DO - 10.1515/afe-2015-0097 KW - Hot-dip galvanizing KW - Ductile iron KW - surface roughness A1 - Kopyciński, D.
