Coordinator: Galusková Dagmar, Ing. PhD.

Team: Galusek Dušan, prof. Ing. DrSc., Chromčíková Mária, Ing. PhD, Michálkoá Monika, Ing. PhD., Švančárek Peter, Mgr. PhD., Prnová Anna, Ing. PhD., Valúchová Jana, Ing. PhD, Chovvanec Jozef, Ing.

PhD., Michalková Jaroslava, Ing., Petríková Ivana, Ing., Škvarková Natália, Ing., Aleksandra Nowicka, Mgr., Švančárková Anna, Ing., ÚACh SAV, ÚMV SAV

Funding 2017: 24681,-EUR

Dates: 2016 – 2020

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.

Dates: 2013 – 2017

Abstract: The main purpose of the project is preparation, development and optimization of mechanical (hardness, strength, fracture toughness, wear resistance), high temperature (corrosion and thermal shock resistance) and electrical (electrical conductivity) properties of silicon carbide based ceramic composites with metallic additives, in a way that would ensure electrical metal-like conductivity without compromising structural stability. As experimental materials SiC composites with various volume fraction of Nb and Ti will be used. The subject of the study will be the relationship between the relevant properties of the experimental materials and parameters of their microstructure with the aim to understand their mutual connections, and then to use the gained knowledge in development of optimal material for applications in civil and electrical engineering.
