“…Figure a shows the XRD results. The polished surface exhibited a typical amorphous feature, but some crystalline phases, such as ZrO 2 , TiO 2 , CuO, Zr 2 Cu, and Cu 10 Zr 7 , were detected on the laser-ablated surface (SI = 50 μm). − The formation of metallic oxides (ZrO 2 , TiO 2 , and CuO) was another possible source of the superhydrophilicity of the laser-ablated surfaces. Accordingly, achieving superhydrophilicity of Zr-based MG surfaces by nanosecond laser ablation depends on the formation of both hierarchical micro/nanostructures and metallic oxides.…”

Tuning the surface wettability and adhesion of metallic glasses (MGs) is a promising approach to enrich their engineering applications. In this study, using nanosecond laser ablation in air, hierarchical micro/nanostructures were directly fabricated on a Zr-based MG surface. Following subsequent annealing, the surface exhibited superhydrophobicity (maximum contact angle: 166°, minimum sliding angle: 2°). Furthermore, the superhydrophobic surface could be tuned from low to high surface adhesion force by controlling the laser-ablated spot interval. By analyzing the laser-ablated structures and surface chemical compositions, the superhydrophobicity was related to the formation of hierarchical micro/nanostructures and the absorption of organic compounds with low surface free energy in air, and the change in surface adhesion force was attributed to the difference in surface roughness. The experimental results showed that the superhydrophobic surface with low adhesion force could be used in self-cleaning applications, while the superhydrophobic surfaces with different adhesion forces could be used in no-loss liquid transportation. This study provides an efficient and low-cost way to fabricate superhydrophobic MG surfaces with tunable adhesion, which will broaden the functional applications of MGs.

“…[21] Zhang et al reported that in contrast to most metallic glasses, a Ti-Zr-Hf-Cu-Ni-Be high-entropy metallic glass exhibited decreased mass gain during prolonged oxidation after the early increased mass gain stage, implying that initially formed oxides are unstable. [22] Moreover, the very early Cu 64 Zr 36 metallic glass oxidation stage, within nanoseconds and cannot be experimentally observed, obeys the inverse logarithmic law according to molecular dynamics simulations, suggesting that ionic drift through the oxide controls oxidation in response to electric fields. [23] When metallic glasses are exposed to humidity, hydroxides considerably change the oxidation kinetics.…”

Owing to their unique structure and outstanding properties, metallic glasses are a novel class of structural and functional materials with vast application prospects. However, the metastable amorphous structures and chemical activity of metallic glass constituent elements lead to frequent oxidation during preparation, processing, and application. Comprehensively understanding the oxidation behaviors and underlying mechanisms of metallic glasses is essential for gaining knowledge of metallic glass structures and properties and for promoting engineering applications. Although many studies have examined these issues, more investigations are still required to explore potential industrial applications of metallic glasses. Here, recent research on metallic glass oxidation is consolidated by summarizing the oxidation influence on metallic glass structure, performance, and application and the possibilities and feasibility of oxidizing metallic glasses to reinforce materials or develop material systems are discussed.
