Reducing Additive Product Surface Roughness by Electrochemical Processing Methods

Abstract

The article considers the problem of improving the quality of the product surfaces obtained by selective laser melting. The possibilities of applying the method of electrochemical and electrolytic-plasma polishing for these purposes are described. The scheme and description of the experimental setup are given, as well as data on the technological parameters of processing, allowing efficient implementing the methods of electrochemical and electrolytic-plasma polishing. The experimental data obtained during processing additive parts, in particular, the profilograms of surface irregularities and roughness indicators, such as the roughness class and the arithmetic mean deviation of the irregularity profile, are analyzed. Proposals for the application of these processing methods in practice are put forward. Perspective directions for the development of the proposed methods for processing additive parts, primarily of complex shape, are considered.
