Current-conducting coatings based on heat-resistant titanium compounds obtained by self-propagating high-temperature synthesis

Titanium carbide, silicide, and carbosilicide are obtained by self-propagating high-temperature synthesis. The microstructure, phase composition, and properties of these compounds are given. Materials in the form of powders were used to form current-conducting polymer doughs. The influence of the type and content of the filling agent, the temperature of the thermal treatment, and the composition of the polymer binder on the electric resistance of polymer coatings is investigated. It is established that the binders that provide the lowest resistance of doughs are PMPP and PPG polymers, and the corresponding filling agent is titanium carbosilicide. The working temperature of doughs containing PMFP and PFG should not exceed 250°C, that of SKTN should not exceed 150°C, and the mixture of epoxy resin and PMFP and PFG should not exceed 300°C.
