In the presented paper the subject related to the heat treatment (HT) of hot-dip zinc coating was initiated. Authors assumed that in the future widely understood optimization of coating HT will results in both mechanical as well as functional properties improvement. Investigations were focused on the hot-dip zinc coating deposited at industrial conditions (acc. PN-EN ISO 10684) on the Fe-C alloys surface (steel and cast iron). In the paper beside basic information: microhardness measurements, optical microscopic observation also examples of EDS after HT are enclosed. It was stated that although the applied HT results in coating hardness increase, the too high temperature level may cause coating cracking and delamination. As the processing temperature increases, the coating structure changes - the iron content in individual Zn phases increases. Zinc coating deposited on cast iron is more inhomogeneous.Keywords: Hot-dip zinc coating, heat treatment, surface quality
