| Abstract (English): |
TiSiCN coatings were prepared with the multi-arc ion plating and magnetron sputtering technique. The effect of the N2/Ar flow ratio on the properties of TiSiCN coatings was studied using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and a friction and wear tester (UMT-3). With an increase in the N2/Ar flow ratio, the number of large particles on the surface first increases and then decreases. The intensity of the TiN (200) diffraction peak increases gradually, while the grain size first decreases and then increases. A TiSiCN coating consists of Ti (N, C) nanocrystallites, amorphous SiC, Si3N4 and carbon. When the N2/Ar flow ratio is 5: 1, the coating exhibits the highest hardness and excellent wear resistance.

| Abstract (Slovenian): |
Avtorji v članku opisujejo pripravo trdih prevlek na osnovi TiSiCN s tehnikama večobločnega ionskega platiranja in magnetronskega naprševanja. Raziskovali so vpliv razmerja med dušikom in argonom (N2/Ar), uporabljenega v pretoku zaščitnega plina, na lastnosti izdelanih TiSiCN prevlek. Študije so izvajali s pomočjo vrstične elektronske mikroskopije (SEM), rentgenske difrakcije (XRD), rentgenske fotoelektronske spektroskopije (XPS) in tornih ter obrabnih preizkusov na univerzalnem večfunkcionalnem trenjsko-obrabnem testerju (UMT-3; angl.: Multifunctional friction and wear tester). S povečanjem vsebnosti dušika v pretakajoči se plinski mešanici, je število velikih delcev na površini najprej naraslo in nato padlo. Intenziteta TiN (200) difrakcijskega pika je postopno naraščala, velikost kristalnih zrn pa se je najprej zmanjševala nato pa postopno naraščala. Ugotovili so, da so izdelane TiSiCN prevleke sestavljene iz nanokristalov Ti(N,C), amorfnega SiC, Si3N4 in ogljika. Ko je bilo v plinski mešanici uporabljeno razmerje N2/Ar 5: 1 je imela prevleka največjo trdoto in odlično odpornost proti obrabi. [ABSTRACT FROM AUTHOR] |
