| 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 coatings—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%. |
