In the present work, a feasibility study was conducted to demonstrate the protective effect of argon in the process of detonation spraying of titanium. Argon was selected as a carrier gas to preserve metallic titanium in the deposited layers. Usually, the detonation gun is not enclosed in a chamber with a controlled atmosphere and it is not obvious whether an inert carrier gas will help reduce the concentration of the reaction products in the deposits. The experiments showed that partial conversion of titanium into nitrides still occurred. At the same time, the use of argon instead of nitrogen allowed substantially reducing the concentration of titanium nitride in the deposited layers. As titanium partially reacted with nitrogen of the surrounding air, titanium nitride of facecentered cubic structure formed as two phases with different lattice parameters. The lattice parameter of titanium nitride contained in the coatings was higher than that of stoichiometric TiN, which indicates a highly defect state of the in-situ synthesized compound.
