Tribological properties and wear mechanisms of ex-situ additively manufactured FeCrMoCB/Cu bulk metallic glass composite (BMGC) under different normal loads and sliding speeds were investigated. The unique amorphous/crystalline microstructure provided FeCrMoCB/Cu BMGC with well wear resistance including low wear rate and coefficient of friction (COF). Both the wear rate and COF showed the same tendency as the variation of normal load. However, the COF decreased but the wear rate increased with the increasing sliding speed. Moreover, the wear mechanisms changed from abrasive wear to oxidation wear and adhesive wear when increasing the normal load, while the adhesive wear and fatigue wear became dominated as the sliding speed increased.

研究了异位增材制造的 FeCrMoCB/Cu 块状金属玻璃复合材料 (BMGC) 在不同法向载荷和滑动速度下的摩擦学性能和磨损机制。独特的非晶/结晶微观结构为 FeCrMoCB/Cu BMGC 提供了良好的耐磨性，包括低磨损率和摩擦系数 (COF)。磨损率和 COF 均表现出与正常载荷变化相同的趋势。然而，随着滑动速度的增加，摩擦系数降低，但磨损率增加。此外，随着正常载荷的增加，磨损机制从磨粒磨损转变为氧化磨损和粘着磨损，而随着滑动速度的增加，粘着磨损和疲劳磨损成为主导。
