Abstract
The research results of d- metal mass transfer under steel 45 electrosparking alloyage are presented. The formed surfaces were investigated with the X-ray structured method, the anode materials, intermetalids, as well as the oxides and nitrides of alloyed metals and iron were discovered. The mechanical properties of formed coverings were investigated. It was determined, that the presence of the products with the secondary structure brittle destruction worsens the alloyage efficiency and properties of coverings. It is most effective to use chrome, nickel and vanadium for forming surface layers, because these metals and iron form unlimited solutions. The correlation between the electrosparking alloyage efficiency and the anode materials thermo- physical properties and atomic characteristics was determined.
