Simulation of current output during chrome plating of parts for hardening and car parts restoration

Introduction. Conducting an experiment when conducting research on electroplating coatings requires a lot of time and energy. To reduce the number of experiments performed, it is necessary to conduct mathematical modeling of the experiment to reduce the number of experiments performed and reduce it to a specific algorithm to obtain reliable and accurate data. The obtained reliable data will allow to get good results in studies of obtaining chrome coatings, with maximum performance, including current output.

Materials and methods. To conduct the research, the necessary equipment for obtaining electroplating coatings, developed a new electrolyte composition for obtaining high-quality high-performance chrome precipitation, as well as the Statistica 13.0 program, which allowed us to reduce the time for calculations and building the necessary graphs, was used.

Results. The analysis of methods and methods of mathematical analysis of the results obtained in order to process them and build a model showed that with a confidence regression coefficient of 0.95, it is most preferable to study the effect of the composition of the chromating electrolyte on the current output, in the range of current density values from 125 ... 250 A / dm2 , the amount of hydrofluoric acid 0.6...1.2 g / l and the operating temperature of the electrolyte 16 ... 27 o C.

Discussion and conclusion. As a result of the obtained mathematical model, it can be argued that studies of the influence of the electrolyte composition on the current density will allow to obtain reliable data with the least number of experiments. At the same time, it can also be argued that it is possible to obtain an even greater current output if additional research is carried out with a change in factors up or down. However, it is not known how the quality of the coating and the adhesion to the base of the part will change, which is an important factor in obtaining wearresistant electroplating.
