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.

Abstract: Transparentné polykryštalické keramické materiály s luminiscenčnými vlastnosťami predstavujú vďaka lepším mechanickým vlastnostiam a vďaka nižšej cene náhradu za monokryštály pre tuhé lasery a scintilátory. Pre dosiahnutie transparencie vo viditeľnej oblasti je potrebné pripraviť polykryštalický materiál s kompletne eliminovanou pórovitosťou. Pre dosiahnutie kvalitných mechanických vlastností, najmä pevnosti a tvrdosti, ktoré vedú k zvýšeniu odolnosti voči teplotným šokom je potrebné pripraviť materiály s jemnozrnnou, ideálne submikrónovou mikroštruktúrou. To je v protiklade s požiadavkou na odstránenie pórov, vyžadujúcou použitie vysokých teplôt a dlhých časov spekania. Projekt je zameraný na štúdium fundamentálnych aspektov spekania materiálov s kubickou kryštálovou mriežkou, najmä yrito hlinitého granátu, dopovaného opticky aktívnymi prísadami a optimalizáciou parametrov jeho prípravy s cieľom pripraviť transparentné materiály s luminiscenčnými vlastnosťami a výnimočnými mechanickými vlastnosťami.

APVV-SK-FR-2017-0008, Corrosion and low temperature degradation of zirconia
Coordinator: prof. Dušan Galusek, DrSc.
Dates: 2018 – 2019
Abstract: The excellent mechanical properties of zirconia-based materials combined with their superior aesthetics and biocompatibility characteristics have encouraged their application as bioceramics, particularly in the dental field. However, this ceramic can undergo Low Temperature Degradation (LTD) in presence of water (ageing) under in-vivo conditions within time scale of the orders of years. To date, only few works have studied the influence of different pH values on zirconia surface features and the effect of acid corrosion on accelerating the process of ageing remains controversial. This project aims to study and elucidate the role of corrosion on LTD regarding zirconia bioceramics that could be used in the dental field but also in other biomedical applications (hip joint, spine prostheses…).Expected results of the project are as follows: (a) Mechanisms of corrosion under experimental conditions will be determined and the influence of long term corrosion on LTD elucidated. (b) Material’s parameters responsible for different corrosion and LTD rates in tested zirconiabased biomaterials will be established. (c) A set of recommendations for zirconia-based biomaterials with decreased susceptibility to corrosion and LTD will be proposed.

APVV 0108-12, Development of SiC based Conductive Ceramics
Coordinator: prof. Dušan Galusek, DrSc.
Team: Galusková Dagmar, Ing. PhD., Kraxner Jozef, Ing. PhD., ÚACh SAV, ÚMV SAV
Funding 2017: 11848,- EUR
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.

- VEGA 2/0058/14: Keramické vrstvy pripravené z organokremičitých prekurzorov pre vysokoteplotnú protikoróznu ochranu kovov
Coordinator: Ing. Dagmar Galusková, PhD.
Dates: 2014 – 2016
Abstract: Korózia kovov v horúcich korozívnych plynoch skracuje životnosť technologických zariadení (výmenníkov tepla v elektrárňach a spaľovniach komunálneho odpadu) a vyžaduje dodatočné investície do ich obnovy. Projekt si kladie za cieľ vývoj nového druhu protikoróznej ochrany – keramických povlakov pripravených riadených rozkladom organokremičitých prekurzorov. Navrhovaný spôsob prípravy umožňuje nanášať vrstvy technológiami, ako sú striekanie a namáčanie v tekutom prekurzore, s následnou pyrolýzou a konverziou prekurzora na amorfnú keramiku. Zmena objemu pri konverzii prekurzora sa kompenzuje prídavkom aktívnych a pasívnych plnív na báze oxidových skiel pripravených plameňovou syntézou vo forme mikroguličiek. Takto pripravené vysokotaviteľné sklá s definovaným zložením zabezpečia účinnosť protikoróznej ochrany do vysokých teplôt (> 1200 oC), optimálnu kompatibilitu plniva s keramikou, a vzhľadom na sférický tvar sklených mikročastíc, aj minimálny negatívny vplyv na reológiu prekurzora pri nanášaní.
