Title: Ecological Aspects of Electro-spark Deposition Technologies for Improvement of the Metal Surfaces Quality Prepared by 3D Printing. Part II. Composition, Structure, Durability, and Environmental Compliance
Keywords: Additive technologies (ATM), electro spark deposition (ESD),

Abstract: Additive technologies (ATM) are one of the most promising ways to reduce environmental pollution and solve various environmental problems. The paper investigates the possibility of improving the surface of ATM products through low-energy electro spark deposition (ESD) with low-melting AlSi electrodes. The research work consists of two parts. In the first part a considerable decrease in the roughness and surface defect of metal alloys based on Ti and Fe has been achieved by ESD. This section examines the impact of ESD regime on the composition, structure and wear resistance of coatings. The conditions for ESD have been determined and optimised in which as a result of the targeted synthesis of new wear resistance phases and amorphous-crystalline structure a simultancous reduction of roughness and surface defects and increase of wear resistance of treated surface are realised.
