Abstract

The use of additive technologies for the production of parts is one of the main trends in recent years in the field of industrial production. Application of the technology of «layer-by-layer growing» provides savings in materials, a significant reduction in labor intensity, and allows you to create parts of any complexity and configuration.

To reduce the surface roughness values of parts manufactured using additive technology, the authors proposed a method of electrochemical treatment in acid electrolytes, which makes it possible to achieve a decrease in surface roughness values by more than 5 times compared to the original one, and to process parts of any complexity and configuration.
