Разработка технологии электрохимического полирования заготовок, полученных методом селективного лазерного сплавления

Abstract

Relevance: Additive technologies based on the layer-by-layer build-up method are very popular in knowledge-intensive industries. The technology of selective laser melting (SLM - Selective Laser Melting) [1] allows creating products of different configurations from almost any metals and their alloys, and modern SLM equipment (3D printers) has a high degree of automation, accuracy and safety. Despite its many advantages, this technology has not been widely used in aircraft engine manufacturing, as it has a number of disadvantages, one of which is the low surface roughness class, which does not allow the use of products without post-processing.Purpose of work: development of technology of electrochemical polishing of workpieces obtained by selective laser fusion.
