Description
  • Provedená studie ukázala, že morfologie a mikrostruktura tvrdých (<40 GPa) a supertvrdých (>40 GPa) nanokompozitních vrstev Zr-Cu-N silně závisí na obsahu Cu. Vrstvy s nízkým (1-2 at.%) obsahem Cu vykazují sloupcovou mikrostrukturu, zatímco vrstvy s vyšším (>5-6 at.%) obsahem Cu mají globulární mikrostrukturu. Tvrdost vrstev Zr-Cu-N závisí jak na obsahu Cu tak i na struktuře jednotlivých fází nanokompozitu. Nanokompozitní vrstva tvořená 2 nanokrystalickými fázemi ZrN a Cu vykazuje nejvyšší hodnoty tvrdosti (až 50 GPa při 1-2 at.% Cu). (cs)
  • In the present article, we compare the morphology and microstructure of hard and superhard Zr-Cu-N nanocomposite films. It is shawn that the morphology strongly depends on the Cu content in the film. The film with a low Cu content exhibits a columnar structure. In contrast, films with a higher Cu content have a globular structure. The hardness of films depends on both the Cu content in the film and the structure of individual phases of the nanocomposite. The nanocomposite film of type nc-/nc- exhibits higher hardness than that of type nc-/a-; here nc- and a- denote the nanocrystalline and amorphous phases, respectively. The film of type nc-ZrN/nc-Cu with a low content exhibits the highest hardness of 50 GPa.
