The study of heat and electrophysical properties in the system ‘stainless steel–glass-ceramic coating’ is carried out. Insulating coatings based on the glass-ceramic material of the PbO–ZnO–B2O3 system are synthesized on stainless steel substrates. The temperature dependences of the dielectric loss tangent and dielectric constant of the obtained functional coatings are investigated. The heat capacity, thermal diffusivity and thermal conductivity of the coatings are investigated using a laser flash analysis. These properties are then compared to ones of the substrates. By the method of differential thermal analysis, the optimal modes of heat treatment of glass-ceramic coatings are established. An optimal material with the best electrophysical properties is revealed. Possibilities of using dielectric coatings as functional layers for film heating elements are analysed.
Key words: glass-ceramic material, insulating coatings, thermophysical properties, film heating element.
