Title: Possibilities for improving the surface quality of structural steels, invar and titanium alloys through reactive electrospark treatment with electrodes of an aluminium-silicon alloys
Keywords: additive technologies, selective laser melting, surface char

Abstract: In the rough and semi-pure processing of metal alloys, as well as in additive technologies, surface defects are often observed - the appearance of scratches, creases, recesses, incisions, pores, ridges, protruding particles, and other unevenness, undesirable spiral or concentric relief, traces of cutting edges of the tool and high roughness on the treated surface. In this work, the possibilities for improving the surface characteristics of materials such as steels, invar and titanium alloys with typical surface defects through reaction electrospark deposition (ESD) are investigated. A study of the conditions for the local formation of reactive phases and reduction of surface roughness during the electrospark modification was performed. Layering electrodes of low-melting AlSi alloys were used. Their choice was made on the assumption that a liquid melt is formed in the process of ESD.
