20.500.12556/RUL-128518 Vpliv procesnih parametrov aluminiziranja na lastnosti modificirane plasti diplomsko delo Influence of parameters of the aluminizing process on the properties of the modified layer diploma work Osnovni namen diplomske naloge je bilo povečanje deleža aluminija na površini zlitine FeCrAl in s tem povečati njeno korozijsko obstojnost. Delež aluminija smo povečali z aluminizacijo v zasipu v cevni peči pri temperaturah med 730 °C in 900 °C ter časih žarjenja med 2 in 4 ure, z zasipom, ki je vseboval 6 mas. % Al, 2 mas. % NH4Cl in 92 mas. % Al2O3 oz. 2 mas. % Al, 6 mas. % NH4Cl in 92 mas. % Al2O3. Po procesu smo analizirali mikrostrukture in izmerili mikrotrdoto z Vickersovo metodo. Osrednji cilj raziskav je bil preučiti mikrostrukturo (nastale faze) ter globino difundiranega aluminija. The main objective of my thesis was to increase the weight percentage of aluminium on the surface of the FeCrAl alloy and thus increase its corrosion resistance. Aluminization was carried out by a pack cementation process in a tube furnace at a temperature between 730 °C and 900 °C at different annealing times between two and four hours in a pack containing 6 wt.% Al, 2 wt.% NH4Cl in 92 wt.% Al2O3 and 2 wt. % Al, 6 wt. % NH4Cl in 92 wt. % Al2O3. After the process, we analyzed the microstructure and measured the microhardness using Vickers method. The main objective of the research was to study the microstructure and depth of diffused aluminium. aluminizacija v zasipu difuzija mikrotrdota zlitina FeCrAl povečanje korozijske obstojnosti mikrostruktura pack cementation diffusion microhardness FeCrAl alloy increase of corrosion resistance microstructure true false false [N.
