Application of Complex Concentrate of Rare-Earth Elements for Obtaining Electrometallic Coatings

Abstract:

The unique physical and chemical characteristics of rare earth elements make them attractive for use in a number of existing and innovative production lines. The use of complex concentrates of various deposits to obtain new materials is a promising area of modern materials science. The article presents the results of studies of electroarc metallization coatings of flux-cored wires with modifying additives. As additives, a complex concentrate of rare-earth metals from the deposits of the Republic of Sakha (Yakutia) and other modifying powders were used to obtain hardening phases. To determine the optimal composition of the modifying additives, various compositions of cored wires were made. An analysis of the structure of coatings showed a uniform distribution of the main elements of the cored wire, as well as a local distribution of unmelted particles of the modifying additives. The levels of open porosity and microhardness of the phase components of the coatings are determined. The prospects of using complex concentrate with rare-earth elements from deposits of the Republic of Sakha (Yakutia) as modifying additives for coatings with enhanced performance properties is shown.
