Fe和Cr被认为是铜基复合材料（Cu-BC）中两个最重要的摩擦组元。本文对含Fe、Cr的Cu-BC进行了微观组织检测和宏观、微观摩擦学性能评价。结果表明，Fe和Cr均与铜基体形成扩散界面。由于缺陷界面层的产生，Cr/Cu界面表现出较低的结合强度。由于Fe和Cu之间良好的结合界面、Fe的高摩擦系数（COF）以及Fe促进的机械混合层的形成，含Fe的Cu-BC在所有单位面积制动能量（BEPUA）值下均表现出更好的摩擦性能。随着BEPUA的增加，含Fe和Cr的Cu-BC的主要磨损机制由磨粒磨损转变为分层磨损，含Fe的Cu-BC的分层磨损是由机械混合层（MML）的断裂引起的。
Fe and Cr are regarded as two of the most important friction components in Cu-based composites (Cu–BCs). In this study, the microstructural detection and micro- and macro-tribology evaluation of Cu–BCs containing Fe and Cr were performed. The results indicated that both Fe and Cr formed diffusion interfaces with the copper matrix. Because of the generation of a defect interface layer, the Cr/Cu interface exhibited a low bonding strength. Owing to the excellent binding interface between Fe and Cu, the high coefficient of friction (COF) of Fe, and the formation of a mechanical mixing layer promoted by Fe, the Cu–BCs containing Fe presented better friction performance under all braking energy per unit area (BEPUA) values. The main wear mechanism of Cu–BCs containing Fe and Cr changed from abrasion to delamination with an increase in BEPUA, and the delamination of Cu–BCs containing Fe was induced by breaks in the mechanical mixed layer (MML).
