Summary: | The wear resistance of stabilized zirconias was investigated on both a pin-on-disk machine and a Dangoumeau apparatus under dry and lubricated (water) conditions. Under the experimental conditions (80 N load and 12 mm/s speed) the wear mechanism can be described as initial plastic deformation and then grain pull-out. The role of the third-body in the interface of friction has been demonstrated with asymmetric couples where one of the antagonists is made of alumina. If for pure friction it is not easy to differentiate the magnesia partially stabilized zirconias (MgPSZ) from the yttria tetragonal zirconia poly crystal (YTZP), after shock tests we can conclude that the YTZP have a better wear behaviour than the MgPSZ, especially in the case of attrition applications. |
