摘要：
The results of research into the effect of stoichiometry on the properties of titanium nitride thin-film coatings on the components of floated and electrostatic gyroscopes are presented. The article also considers the results of research into the mechanical and optical characteristics of titanium nitride thin-film structures: microhardness, resistance to wear and friction, and image contrast, which is determined by the reflection coefficients of the titanium nitride base surface and the raster pattern generated by the method of local laser oxidation. The future and technological methods of generation of functional surface structures of niobium carbide and niobium nitride in the process of development of a rotor of a cryogenic gyroscope are discussed. It is shown that the formation of a coating of required composition requires a thermodynamic assessment of possible interactions during which structural-phase modification of the material is carried out, determined by the complex of possible topochemical reactions leading to the formation of compounds, including the ones with nonstoichiometric composition. © 2020, Pleiades Publishing, Ltd.
