Study of High-Performance Chromium Electrolyte for Restoration of Automobile and Road-Construction Machinery Parts

The conducted studies of high-performance self-regulating cold chromium electrolytes showed that they have a number of difficulties for implementation - the complexity of their organization and implementation in production. As a basic high-performance chromium electrolyte we used the existing chromium electrolyte, whose productivity and current output falls, as well as the quality of the deposit decreases when the working temperature of the electrolyte exceeds 30°C. To solve this problem the composition of the electrolyte was changed, which allowed to eliminate the existing drawbacks. As a result of the research and the results obtained it was found that the new composition of chromium electrolyte on the basis of the existing one in the working temperature range of 18-35°C would increase the current output to 50% and increase the deposition rate to 450 mkm/h, with improved quality of coatings in thickness, while maintaining high microhardness and wear resistance. Therefore, the developed electrolyte will be possible to use for restoration of parts of motor vehicles and road-construction machinery.
