The possibility of using carbonate manganese ore from Chiatura Deposit (Georgia) in the glass enamels industry is described. The nonfluor multicomponent manganese-containing glasses have been designed. Their chemical stability has been established according to ASTM C650. It is shown, the chemical durability of all glasses to inorganic acid is strongly dependent upon the SiO2 content in glasses. The kinetic analysis of glass materials corrosion processes was presented. The roughness parameters responsible for deposit growth on investigated surface are analyzed. The optimal glass composition was used to obtain high-quality tracks in the “metal-vitreous enamel” system. Upgraded cost-effective enamel coating may initially provide adequate protection of steel pipes and can be recommended for testing on pipelines.
