Abstract

The paper deals with evaluation of quality of electrolytic coating by statistical methods. Electrolytic solution was created by ZnCl₂ within interval of 0,062 mol·l-1to 1,01 mol·l-1, NaCl ranging from 7,01 mol·l-1 to 60,66 mol·l-1, H₃BO₃ ranging from 0,11 mol.l-1 to 0,89 mol.l-1. Physical conditions of the experiment are represented by the electrolyte temperature ranging from - 3,78 °C to 43,78 °C, electroplating period ranging from 3,11 to 26,98 min and voltage ranging from 1,62 V to 6,38 V. Steel S355J0 was used as an experimental material. The results showed that zinc chloride volume contained in the electrolyte does not produce any influence on resulting quality of zinc coating.
