ABSTRAKT

In the present work compression plasma flows (CPF) were used for synthesizing Nb-containing surface layers in an aluminum−silicon eutectic alloy, Ti−WC−Co hard alloy, and a Ti alloy. The investigation results of the structure, phase composition, and mechanical properties of the formed alloyed surface layers are presented. The findings showed that plasma impact on the Nb/material system leads to the formation of a Nb-alloyed surface layer containing different phases with Nb: solid solutions, intermetallides, nitrides, carbides, and carbonitrides. Alloyed layers have an increased hardness.
