Abstract

U teorijskom dijelu ovog rada sažeto su opisani alatni čelici, superlegure, postupci modificiranja i prevlačenja površina, a posebno postupak plazmom potpomognutog kemijskog prevlačenja u parnoj fazi (eng. Plasma Assisted Chemical Vapour Deposition – PACVD). U eksperimentalnom dijelu ovog rada provela se osnovna toplinska obrada te prevlačenje PACVD postupkom prevlakom titan nitrid (TiN) na tri ispitna uzorka od tri različite vrste čelika. Nakon toplinske obrade provedena su ispitivanja tvrdoće i toplinske vodljivosti. Na kraju rada prikazani su rezultati navedenih ispitivanja te je izvršena analiza istih. Iz rezultata se može zaključiti da FASTCOOL inovativni čelici unatoč sličnoj tvrdoći imaju značajno veću toplinsku vodljivost u odnosu na alatni čelik za topli rad X38CrMoV5-1.

Abstract (english)

In the theoretical part of this work, tool steels, superalloys, surface modification and coating processes, and especially the plasma assisted chemical vapor deposition process (PACVD) are briefly described. In the experimental part of this work, basic heat treatment and PACVD coating with titanium nitride (TiN) coating was carried out on three test samples of three different types of steel. After heat treatment, hardness and thermal conductivity tests were performed. At the end of the paper, the results of the mentioned tests are presented and an analysis of them was performed. Based on the results, it can be concluded that FASTCOOL innovative steels, despite their similar hardness, have significantly higher thermal conductivity compared to hot work tool steel X38CrMoV5-1.
