Abstract

abstractEN: The paper presents preliminary results of research on theproduction of composite coatings from the Fe-Al systemwith participation of intermetallic phases in-situ using arcspraying. The spraying process was carried out by simultaneouslymelting two different electrode wires, aluminium andsteel. The aim of the research is to create protective coatingswith a composite structure with a significant participationof FexAly as a intermetallic phases reinforcement. The synthesis of intermetallic takes place during the (in-situ) spraying process. Currently most of coatings involving intermetallic phases are being manufactured by different thermal sprayingmethods using coating materials in form of prefabricatedpowders containing intermetallic phases. The obtained results showed that the local occurrence of intermetallic phases from the Fe-Al system, and the dominant componentsof the structure are two phases, aluminium solid solutionsin iron and iron in aluminium. The participation of intermetallic phases in the coating is relatively low, but it’s effecton the properties of the coating material is significant.score: 9collation: 62-6
