Essay

The dissertation is devoted to developing and improving methods of projecting compositions of oxide glasses with the given complex of properties as well as to developing glasses based on these compositions for obtaining electroinsulating glass- and glass-ceramic coatings for streamline heater elements made of low-carbon steel and aluminium substratum. In work the researches for determinating interrelation between temperature, frequency of alternating electric field, chemical composition and properties of glasses and melts influencing the formation of a quality electroinsulating coatings have been carried out. The researches involved have formed the basis for projecting compositions of glasses in question. The mathematical models developed are new and allow to calculate specific electric resistance, dielectric penetration, dielectric loss, softening temperature, molecule volume of glasses, temperature linear expansion coefficient of glass-ceramics materials, viscosity and surface tension of borosilicate melts with higher accuracy and within wider limits of containing components than the known methods. Using the received mathematical models substantiated choice of optimal compositions of basic glasses for obtaining electroinsulating glass- and glass-ceramic coatings for low-carbon steel and aluminium has been done. The compositions of enamel slips and technological characteristics for obtaining electroinsulating glass- and glass-ceramics coatings of low-carbon steel and aluminium have been developed.
