Corrosion trends in the bulk metallic glass forming alloy system Zr-Cu-Al are studied through a fast screening visual characterization method of thin film alloy libraries prepared by magnetron co-sputtering. Significant distinct brightness changes are present within the Zr-Cu-Al system when the thin film library is immersed in 3.5 wt % NaCl. Through additional quantification of corrosion current density, a correlation between change in brightness and corrosion current density is revealed, suggesting an effective rapid screening of corrosion simply by a visual method. For materials discovery with optimized multiproperties, we utilize the corrosion fast screening results and superimpose them on the composition dependence of the glass forming ability. This allows us to rapidly identify alloys with the best combination of glass forming ability and corrosion resistance, which we then confirm in bulk form.

快速筛选金属玻璃中的腐蚀趋势。

通过磁控共溅射制备的薄膜合金库的快速筛选视觉表征方法，研究了块状金属玻璃成形合金体系Zr-Cu-Al的腐蚀趋势。当薄膜库浸入3.5 wt％的NaCl中时，Zr-Cu-Al系统中会出现明显的亮度变化。通过对腐蚀电流密度的进一步量化，揭示了亮度变化与腐蚀电流密度之间的相关性，表明仅通过视觉方法即可有效地快速筛选腐蚀。对于具有优化多特性的材料发现，我们利用了腐蚀快速筛选结果，并将其叠加在玻璃成型能力的成分依赖性上。
