This article considers the research results of the effect of stoichiometry on the properties of titanium nitride thin-film coatings of the float and electrostatic gyroscopes. It presents the results of tests of such mechanical and optical characteristics of titanium nitride thin-film structures as microhardness, resistance to wear and friction, and image contrast determined by the reflection coefficients of a titanium nitride base surface and a raster pattern formed by local laser oxidation. When making a rotor of a cryogenic gyroscope, the prospects of use and technological methods for the formation of functional surface structures of niobium carbide and nitride are considered. It is shown that during the formation of coatings of the required composition, the most important is the thermodynamic estimation of possible interactions. These interactions allow us to accomplish the structural-phase modification of the material, which is determined by the complex of possible topochemical reactions leading to the formation of compounds, including non-stoichiometric composition.

Thin film of TiO2 on graphite substrat has been prepared by means of chemical bath deposition. Cetyltrimethylammonium Bromide served  as linking agent of synthesized TiO2 to graphite substrate.The optical microscope and Scanning Electron Microscope (SEM) indicate that surfactant concentration affects the pore morphology of thin film Surface Area Analysis (SAA) of thin film indicated that the pore of thin film included in mesopore category. The anatase phase of TiO2 quantity arised as the surfactant concentration increase, gave high efficiency of induced photon conversion to current efficiency (% IPCE).   Keywords: thin film, TiO2, deposition, graphite
