Abstract The tribological behaviors of the high-performance Cu36Zr48Ag8Al8 bulk metallic glass (BMG) under dry-sliding, deionized water and NaOH solution conditions were systematically investigated and the corresponding wear mechanisms were revealed via analyzing the chemical composition and topography of wear track. The results illustrate that the Cu36Zr48Ag8Al8 BMG exhibits tribological properties superior to those of 316 stainless steel under different friction conditions, especially in a NaOH solution. During friction sliding, the formation of uniform and continuous metal-oxide layers on the surface can enhance its wear resistance and protect it from further corrosion by OH−. Furthermore, the NaOH solution and the dissolved products on the frictional surface form fluid-lubricating films, which may also reduce the friction coefficient and wear rate of the material.

Cu36Zr48Ag8Al8块状金属玻璃在干滑动、去离子水、NaOH腐蚀溶液等不同滑动条件下的滑动摩擦磨损机理

摘要 系统研究了高性能Cu36Zr48Ag8Al8块状金属玻璃(BMG)在干滑动、去离子水和NaOH溶液条件下的摩擦学行为，通过分析磨损轨迹的化学成分和形貌，揭示了相应的磨损机制。结果表明，Cu36Zr48Ag8Al8 BMG 在不同摩擦条件下，尤其是在 NaOH 溶液中，表现出优于 316 不锈钢的摩擦学性能。在摩擦滑动过程中，表面形成均匀连续的金属氧化物层可以增强其耐磨性并保护其免受OH-的进一步腐蚀。此外，NaOH溶液和摩擦表面的溶解产物形成流体润滑膜，
