Processing Optimization and Dry-Sliding Tribological Performance of Cu-Ni-Graphite Self-Lubricating Composites

Cu-Ni-graphite self-lubricating composites were developed for railway switch slide baseplate applications, which require a low dry friction coefficient and adequate load-bearing capacity under low-speed sliding. The powder-metallurgy route—comprising planetary ball milling, cold compaction, and vacuum sintering—was sys...
