Abstract The sessile drop method has been used to determine the limiting wetting angles for titanium-tantalum carbonitride by metals of the iron subgroup in nitrogen and vacuum. The wetting angle is reduced when one passes from iron to cobalt and nickel, which corresponds to the characteristic variation in θ in the wetting by the iron subgroup metals of pure refractory-metal carbides. X-ray microspectralanalysis indicates the contact interactions in these systems. The limiting wetting angle for titanium-tantalum carbonitride is reduced by comparison with pure titanium carbide on account of tantalum diffusing into the metal in contact with it, as a result of donor-acceptor interaction activation. It is suggested that the Ti0.75 Ta0.25 C0.5 N0.5 — MeVIII sections are quasibinary eutectic ones.
