Characterization of the Oxide Layer Formed on the Cu-Zr Based Metallic Glass during Continuous Heating

Influence of the Oxide and Ethanol Surface Layer on Phase Transformation of Al-Based Nanocomposite Powders under High-Energy Milling

“…A thin oxide layer exists on the surface of both initial powders. If CuZr(Ag,Al), CuZr 2 or amorphous phases are located on a particle surface, the composition of the layer is ZrO 2 [32]. In the case of the Al and Al 0.8 Ag 3.2 phase, the oxide layer is Al 2 O 3 .…”

Bulk metallic glassy surface native oxide: Its atomic structure, growth rate and electrical properties

“…Thermal oxidation of ZrACu-based BMGs was found to follow one of two mechanisms [31]: either nodules of tetragonal ZrO 2 with embedded nanocrystals of other late transition metals (CuO and ZrO 2 oxides on the surface of Zr 55 Cu 30 Al 10 Ni 5 BMG [32] or Cu 2 O, CuO and tetragonal ZrO 2 on CuAZrAAl BMG [33]); or formation of a lamellar structure of the tetragonal and monoclinic forms of ZrO 2 (Cu 50 Zr 50 and Cu 46 Zr 46 Al 8 metallic glasses [34]). On the other hand layers of CuO/Cu 2 O and a minor fraction of cubic-ZrO 2 were formed on Cu-rich Cu 60 Zr 30 Ti 10 metallic glassy surface [35].…”
