Summary:Title screen
The wear of zirconia-based ceramics and WC-based ceramic–metal composites in high-speed dry sliding over steel is examined. The pin-on-disk technique is used up to a sliding speed of 47 m/sec. It is shown that tribolayers with complex composition form over ceramic and metal–ceramic materials and cause nonmonotonic changes in wear and friction. At the first stage, wear changes from normal to extreme high-intensity one with increasing sliding speed. At the second stage, steady-state wear is observed for the metal–ceramic composite and the wear rate of the ceramic material decreases virtually to its initial level typical of low sliding speeds (0.1 m/sec). Practically wearless friction of ceramics is observed over this range of speeds.
