The tribological properties of four different materials are investigated, tetragonal zirconia (Y-TZP), Al 2 O 3 , dispersed in Y-TZP (ADZ), ZrO 2 dispersed in Al 2 O 3 (ZTA) and Al 2 O 3 (with 300 ppm MgO). These materials are used as a cylinder sliding against a plate of Y-TZP (TZ-3Y)). Compared to Y-TZP, the wear resistance of ADZ composites...
This study examines the feasibility of using electron back scattered diffraction (EBSD) as a way of examining the plastic deformation near to wear damage on the surface of a WC/Co hardmetal. Samples were scratched in micro-scratch tests to simulate the type of contact that would occur in abrasion. It was found that EBSD gave clear information that could be correlated with the degree of plastic deformation...
