研究了纳米共晶Fe 1.87C 0.13合金及其粗晶-共晶合金在空气和真空条件下的摩擦学行为。结果表明,两种合金在空气中的磨损率均低于真空中的磨损率,其摩擦系数与载荷和试验气氛有关。纳米共晶Fe 1.87C 0.13合金在两种环境中的磨损率均低于粗晶对应物。在空气和真空条件下,随着载荷的增加,两种合金的磨损率均增加,而摩擦系数均降低。真空条件下的磨损机制主要为粘着磨损,空气条件下的磨损机制主要为氧化磨损,沿着发生轻微的分层。
In this paper, the tribological behavior of nanoeutectic Fe1.87C0.13 alloy and its coarse-grained-eutectic counterpart under air and vacuum was investigated. The results showed that the wear rate of both alloys was lower in air than in vacuum, and their friction coefficient was related to applied load and testing atmosphere. The nanoeutectic Fe1.87C0.13 alloy exhibited lower wear rate than the coarse grained counterpart in both environments. The wear rate of both alloys increased but the friction coefficient decreased with increasing applied load under both air and vacuum. The dominant wear mechanisms were adhesion wear in vacuum but oxidation wear along with slight delamination in air.
