“…Generally, two main processes used to fabricate self-lubricating aluminum composites are (a) solid state processing [76,78,82,[99][100][101][102] and (b) liquid state processing [32,61,63,64,66,80,90,103,104]. The process that is employed to fabricate self-lubricating composites has an effect on the tribological behavior of composites due to variations in microstructure, distribution of graphite, and bonding between matrix and graphite, depending on the process used to manufacture the composites.…”
