Abstract

The wetting kinetics of titanium-chromium diboride and composition materials of (Ti, Cr)B2-AlN, (Ti, Cr)B2-SiC systems by NiAl (VKNA) intermetallic alloy has been studied. It was shown that in such systems the contact angles are equal to 0-20°. The microstructure of interaction area has been investigated. It was established that in (Ti, Cr)B2-VKNA and (Ti,Cr)B2-AlN)-VKNA systems the saturated solid solutions of Ti and Cr in VKNA alloy, and Ni in the substrate of composition material. This testifies about advisability of cermet materials acquisition base on these systems.
