Abstract: Extension of lifetime and enhancing the thermal stability of steel used for construction of exhaust pipes, heat exchangers in waste incinerators, and casting and melting aggregates in steel and glass production can be achieved via suitable anti-corrosion coatings. The aim of this project is development of new types of composite anti-corrosion protective layers, based on ceramics prepared by controlled pyrolysis of organosilicon precursors. The use of organosilicon precursors facilitates application of conventional coating technologies, such as spray and dip-coating, with subsequent pyrolysis and conversion of the precursor to amorphous ceramics. Increased thermal stability, corrosion resistance, and minimization of volume changes related to conversion of the organic precursor to ceramics will be achieved through the addition of suitable active and passive oxide glass fillers prepared by flame synthesis in the form of microspheres. The flame synthesis facilitates the preparation of glasses with high melting point, which ensures increase of the maximum operation temperature of the coating up to 1400 oC, as well as increased oxidation and corrosion resistance of prepared coatings, optimum compatibility of the filler with ceramic matrix and metallic substrate and, due to spherical shape of glass microparticles, also negligible influence on the rheology of the system polymer-filler in the course of coating on metallic substrate.
