摘要

The tribological behaviour of different monolithic and composite ceramics was evaluated in the temperature range between room temperature and 750℃. The test method was oscillating sliding with a ball-on-disk arrangement in an SRV machine. Alumina balls were used as counter body. The friction behaviour was determined on-line, and the wear behaviour was determined from calculations on the basis of wear scar dimensions and profilo-metric measurements. The friction depends on temperature and shows an increase for most materials for increasing temperature; the smallest friction at all temperatures is found for monolithic TiC. The wear behaviour shows different trends for the different materials. In tests against SiC a maximum of wear is found at 500℃, for TiC at 200℃ and for TiB_2 at 750℃. The composite ceramics suffer the smallest wear of all materials in the range from 200℃ to 500℃.
