Abstract
The research results showed that the problem of resource saving during the chromium electroplating from standard electrolyte can be solved. Formulated requirements that ensure the implementation of the set tasks without costs for new equipment and chemical reagents. It has been proved that organic compounds of a certain structure introduced into the electrolyte influence the chromium electroplating in such a way that all technological characteristics, coating properties, physical and chemical characteristics of the solution change. The chrome plating process has been optimized using the experimental mathematical planning method, which made it possible to develop methods for obtaining chrome coatings protected by security documents on the basis of experimental data. All the proposed methods allow solving the problem of resource saving and environmental safety. The authors have consistently studied resource-saving and environmental indicators. In galvanic chromium plating technology, resource-saving indicators are: energy intensity; metal intensity; water intensity; and labour intensity. Environmental indicators: industrial emissions: gas emissions, waste water; occupational diseases.
