MATHEMATICAL MODELING OF THE PROCESS OF ELECTROCHEMICAL DEPOSITION OF Mo-Re

The paper reports the results of mathematical modeling and optimization of the process of obtaining thin films based on Mo-Re alloy by electrodeposition. The study of electrodeposition of Mo-Re alloys was carried out using methods of potentiodynamic, galvanostatic, and cyclic voltammetry under different conditions on a Pt electrode. Studies have been conducted using the method of planning experiments and a regression equation is obtained. Based on the experimental data, the obtained regression equation was analyzed, the Fisher criterion was calculated and the significance of the regression coefficients was estimated. To confirm the experimental results, based on the data obtained, the coefficients of the regression equation were refined, and the criteria of significance and adequacy were calculated. The calculations based on the experimental data indicate that the regression equation adequately describes the process of co-deposition of rhenium with molybdenum.
