Abstract
Zrakoplovstvo je specifična djelatnost čija sveprisutnost ali i specifičnost u današnje vrijeme sve više dolaze do izražaja. Bez obzira na vojnu ili civilnu namjenu zrakoplova, nužno je osigurati visoku razinu pouzdanosti, efikasnosti i sigurnosti. Posebno se takvi zahtjevi odnose na materijale od kojih se izrađuju zrakoplovi i zrakoplovni motori. Jedna od najvećih inovacija bio je razvoj i primjena mlaznog motora. Razvoj ove vrste pogona koja je u temelju promijenila zrakoplovstvo bio je popraćen razvojem čitavog niza novih materijala. Naime, materijali su bili suočeni s visokom razinom očekivanja u kontekstu fizikalnih i kemijskih svojstava. S obzirom na vrlo visoke temperature rada ovih motora, keramički materijali savršen su odgovor na tu problematiku. Obloge na bazi keramičkih materijala trenutno su najbolja rješenja za konstrukciju i izvedbu mlaznih motora. U ovom radu razmatra se jedna vrsta visokotemperaturnog keramičkog materijala: mulit. S obzirom da ga odlikuje cijeli niz odličnih svojstava, mulit se smatra najvažnijom kristalnom fazom klasičnih keramičkih materijala i važnim inženjerskim materijalom. Uzorci istog pripravljeni u laboratoriju podvrgnuti su primarnim tehnikama ispitivanja i analize. Na osnovu rezultata ispitivanja dani su zaključci o mogućoj primjeni ove keramike kao prevlake dijelova turbina mlaznih motora.
Abstract (english)
The aviation is quite specific discipline that nowadays displays increasing omnipresence and importance. Regardless of military or civilian application, necessity to ensure high levels of reliability, efficiency and security remains. Such requirements heavily repose on the constituent materials for aircraft fuselage and engines. Generally, one of the greatest milestones was the development of a jet engine. The development of jet propulsion was accompanied by the development of plethora of new materials with enhanced properties. Namely, materials were facing high levels of both physical and chemical challenges. Having in mind a very high jet engine operating temperatures, the high-temperature ceramic materials emerge as an answer to these requirements. Currently ceramics-based coatings are leading solution for construction of jet engines. This paper deals with one kind of high-temperature ceramics material; the mullite. On behalf of its excellent properties, mullite is considered as the most important crystal phase of classical ceramic materials and an important engineering material. Mullite samples were synthesised and processed to solid bodies and characterised in details. Based on the results of the tests, conclusions on the possible application of this ceramics as coatings of the parts of the jet engine turbine are given.
