摘要	Due to the fascinating application prospects of Zr-based bulk metallic glass (BMG), it is of practical en-gineering interest to study its wear behavior and mechanism under various temperature conditions. In this work, the wear behavior and mechanism of a commercially available Zr35Ti30Be26.75Cu8.25 BMG at room temperature (RT) to 500 & DEG;C were investigated. The results demonstrated that the wear rate increased from-24.7 x 10-5 mm3 N-1 m-1 to-196.8 x 10-5 mm3 N-1 m-1 as the temperature increased from RT to 500 & DEG;C. Accordingly, the coefficient of friction (COF) is reduced from an average of 0.45-0.18 due to the lubricating effect of the oxide layer. At low temperatures of RT and 200 & DEG;C, the predominant wear mechanisms are abrasive wear and adhesive wear. However, in the supercooled liquid region (SCLR) of at 350 & DEG;C, the dominant wear mechanism is a combination of superplasticity-dominated abrasive wear, severe fatigue wear, and slight oxidative wear. Above the crystallization temperature (Tx) at 500 & DEG;C, the primary wear mechanisms are severe abrasive wear and oxidative wear. Our results can provide important guidance for determining the applicable temperature, service life and failure mode of BMG components. & COPY; 2023 Elsevier B.V. All rights reserved.
