Amorphous Zr-Cu thin-film alloys with metallic glass behavior

Popis výsledku v původním jazyce

Binary Zr–Cu thin-film alloys were prepared by non-reactive conventional dc and impulse magnetron co-sputtering using two unbalanced magnetrons equipped with Zr and Cu targets. The magnetron with the Zr target was operated in a dc regime while the magnetron with the Cu target in a pulse regime either at low or high density discharge conditions. The evolution of the structure, thermal behavior, mechanical, electrical and surface properties of Zr–Cu films with increasing Cu content was systematically investigated. We found that Zr–Cu thin-film metallic glasses were prepared with the Cu content between approximately 30 and 65 at.% Cu. The deposition at the high density discharge conditions resulted in a preparation of the Zr–Cu thin-film metallic alloys with a compressive stress (&lt;0 GPa), an enhanced hardness (&gt;7 GPa), very smooth (surface roughness &lt;1 nm) and hydrophobic (water contact angle &gt;100°) surface.
