In this paper, the effect of pv factor on the tribological behavior of a copper-impregnated metallized carbon brush sliding against a CuCrZr ring was investigated. Friction and wear tests were conducted on a brush-on-slip ring type wear tester. The tests were performed at two electrical currents (0 and 20A) and seven different combinations of contact pressure (p) and sliding velocity (v), herein...
Concerns of polyethylene wear debris induced osteolysis has been partially responsible for the renewed interest in the second generation Metal-on-Metal (MoM) hip replacements as an alternative to widely used Metal-on-Polyethylene (MoP) joint prostheses. The total wear loss from MoM is much less than from MoP. However, the number of nano-sized wear particles from MoM is more than a hundred times than...
Based on a work by Knothe et al. a fully analytical solution for the temperature field, produced by sliding contact on the surface of a halfplane, is presented applying the Laplace transform technique. Further, the stress state in the halfplane under plane strain is analysed. A full solution is presented for the whole stress state as well as its extrema. All results are given in dimensionless form...
