Characteristics of Polymetallic Structures Obtained by Direct Metal Deposition of Stainless Steel, Chromium Bronze and Lead for Antifriction Parts

The paper considers the production of bimetallic copper-steel structures with the addition of lead for the formation of functional coatings and the manufacture of parts with high tribological properties and wear resistance by laser direct metal deposition method. Metallographic analysis of the structure of the grown samples has been carried out and a number of features of its formation depending on the quantitative ratio of dissimilar metals in the powder composition has been revealed. The possibility of obtaining alloys of immiscible components with uniform distribution of structural components in the volume by coaxial laser melting has been shown.
