Abstract

Ideja ovog rada bila je istražiti kako prevlačenje čelika utječe na njihovu toplinsku vodljivost. U ovom radu opisani su alatni čelici, pogotovo alatni čelici za topli rad te su uspoređeni s inovativnim FASTCOOL čelicima. Detaljno su opisani postupci prevlačenja, podjele prevlačenja te ponajviše PACVD i PVD postupci. U sklopu ovog rada napravljen je i eksperiment u kojem se mogu uočiti razlike između standardnih čelika za topli rad te novih inovativnih čelika, te također i razlike između njihove toplinske vodljivosti prije prevlačenja i nakon prevlačenja. Cilj rada je donijeti zaključke o utjecaju prevlaka na toplinsku vodljivost čelika.

Abstract (english)

The idea of this work was to investigate how the coating of steel affects their thermal conductivity. In this paper, tool steels, especially tool steels for hot work, are described and compared with the innovative FASTCOOL steels. Coating procedures, coating divisions, and especially PACVD and PVD procedures are described in detail. As part of this work, an experiment was made in which the differences between standard steels for hot work and new innovative steels, as well as the differences between their thermal conductivity before coating and after coating, can be observed. The aim of the work is to draw conclusions about the influence of coatings on the thermal conductivity of steel.
