Abstract
The coating of a high-entropy alloy (HEA) of non-equiatomic composition was formed on a substrate of alloy 5083 using the technology of wire-arc additive manufacturing (WAAM) in an atmosphere of pure nitrogen. Analysis of the structure, elemental composition, micro-hardness, and wear resistance of the coating/substrate system was carried out using the methods of modern physical materials science.
Supporting agencies: The research was supported by the grant of the Russian Science Foundation (project No. 20-19-00452) and the Ministry of Science and Higher Education of the Russian Federation within the framework of the project under agreement No. 075-15-2021-709, the unique identifier of the project RF-2296.61321X0037 (control measurements).
