Cu-based self-lubricating composites have excellent mechanical properties and enhanced friction characteristics, rendering them ideal for aerospace wear parts. However, the significant mismatch in coefficients of thermal expansion (CTE) between them and counterparts, typically steel, would limit their widespread application. To address this issue, Ni50Fe powders with a low CTE are incorporated into Cu15Ni8Sn-MoS 2 composites via mixing and hot-pressed sintering, resulting in Cu15Ni8Sn-Ni50Fe-MoS 2 composites. The addition of Ni50Fe significantl...
