Abstract The bulk metallic glass has the potential application used in mechanical moving parts serving in corrosive environments because of its excellent mechanical, tribological properties and corrosion resistance. Here, Zr48Cu36Al8Ag8 BMG/graphite composites with a 3D lubricating layer are prepared via an in-situ integrated technique. The synergism of the graphite lubrication and the micro-texture effect could significantly smooth the friction coefficient curve and reduce wear. Although seawater has a lubricating effect, the corrosion affects the reliability of BMG/graphite composites. By applying an external potential to the friction system, the effect of preventing galvanic phenomena at the interface between the alloy and graphite and improving the wear resistance of the composite material can be effectively achieved.

具有 3D 润滑层的原位制造块状金属玻璃/石墨复合材料：干滑动和海水中的摩擦学特性

摘要 大块金属玻璃由于其优异的机械、摩擦学性能和耐腐蚀性能，在腐蚀环境下的机械运动部件中具有潜在的应用前景。在这里，通过原位集成技术制备了具有 3D 润滑层的 Zr48Cu36Al8Ag8 BMG/石墨复合材料。石墨润滑和微纹理效应的协同作用可以显着平滑摩擦系数曲线并减少磨损。虽然海水具有润滑作用，但腐蚀会影响 BMG/石墨复合材料的可靠性。通过对摩擦系统施加外部电位，可以有效地达到防止合金与石墨界面处的电偶现象和提高复合材料耐磨性的效果。
