Self‐Lubricating Behavior and Tribofilm Formation of SPSed Iron‐Based Composites Reinforced by Graphite/PbO
Conventional iron‐based materials suffer from severe wear and oxidation over a wide temperature range, compromising their service reliability. In this work, iron‐based self‐lubricating composites containing graphite and PbO were fabricated via spark plasma sintering, and their tribological behavior was systematically i...
