Abstract
In order to improve the corrosion resistance of the material EN 355 the thickness of the zinc coating, deposited during the acid zinc plating process at a constant current density 1 A·dm-2, was monitored. The thickness of deposited coating has been investigated as the relationship of physical and chemical factors acting during the galvanic zinc plating, i.e. the electrolyte temperature, electrolyte composition (the amount of zinc, the amount of chloride and boric acid in the electrolyte), the plating time and the size of the voltage. Based on the mathematical-statistical analysis of the obtained data the suitable predicting model was developed for determining the thickness of deposited zinc coating reflecting the technological conditions of the acid zinc plating process.
