Formation of Electric-Spark Coatings from Composite Materials Based on Titanium-Chromium Carbide and Diboride

摘要

Electrode composite materials of the TiCrB_2-(Fe-Cr) and TiCrC-(Fe-Cr) systems are discussed. The composition, structure, mechanical and tribotechnical properties of the materials have been studied. Coatings from the materials developed have been applied to the 30KHGSA steel and VT3-1 titanium alloy. The effect of the length of electric-spark alloying and electrode and substrate materials on the mass-transfer kinetics has been analyzed. It has been shown that the materials developed can be successfully deposited onto steels and titanium alloys by the electric-spark method.
