SEM imaging of the wear surfaces on the FGO-CMMC (0.25CD) track at the higher load shows increased wear of the misorientated growths, however, the shear-delamination is still dominant: the debris within the tracks is sheared-platelet like (Figure ). This is in contrast to FGO-CMMC (0.5CD) as the micrographs show high rates of wear and microparticle-like debris generation (Figure ). This supports the theory that the more ductile mechanical properties of FGO-CMMC (0.25CD) result in a sliding surface that is more resistant to abrasive wear, promoting a longer-lasting lubricating tribofilm.
