Morphology of wear particles under the lubrication of water and FBS. (a) Plots of the wear rate in water or FBS versus different contact pressures. (b) and (c) SEM images of the PEEK wear particles by rubbing PEEK pin against surface S in water (b) or in FBS (c) under the contact pressure of 3.0, 1.5, and 0.6 MPa. (d) and (e) SEM images of the PEEK wear particles by rubbing PEEK pin against surface L in water (d) or in FBS (e) under the contact pressure of 3.0, 1.5, and 0.6 MPa.
