Abstract

The wear resistance of Ti₄₅Zr₁₆Cu₁₀Ni₉Be₂₀ bulk metallic glass with a deep cryogenic-cycling treatment (DCT) was studied here. The specimens showed increased plasticity and decreased hardness after DCT. The higher wear resistance could be achieved by sacrificing partial hardness in macroscopic wear tests. Morphological observation revealed that the wear mechanism changed from severe fatigue wear to mild ductile ploughing, and the oxidation wear played a mild role. Nano-scratch tests were applied to explore the adhesion and ploughing contributions under the ramping-constant load mode. The competition between the lower hardness and the higher elastic recovery results in the lower friction coefficient. Therefore, DCT has great potential in the application of designing wear-resistant BMGs.
