Abstract: The paper deals with elaborating of a mathematical model of chromium plating process. Chromium is deposited from a non-standard electrolyte containing chloride instead of sulphate ions. The parameters of the model are obtained using the program for Gram-Schmidt regression. Regression equations are derived describing the most important properties of the chromium coatingsā€”hardness (H), brightness (B) and cathodic current efficiency (Ce). The adequacy of the equations is checked and values of the statistic criteria (correlation coefficient and mean square deviation) are determined. The test of the model reveals that the deviations of experimentally established parameters from those calculated using the proposed model are within 8-10%.
