摘要

Zirconia is one of the most versatile structural ceramic materials because of the range of possible microstructures, and hence mechanical properties. Toughened zirconia materials with different microstructures are currently used for tribological applications either in the monolithic forms or as coatings. In the present study, lubricated friction and wear behaviors of five different zirconia materials with different microstructures were evaluated using block-on-ring contact configuration and unformulated PAO lubricant. Tests were conducted with zirconia blocks sliding against hardened steel coated with hard MoN thin film. Although the friction behaviors of the all the tested materials are similar with average friction coefficient of 0.10 - 0.12 for all materials, significant differences were observed in their wear attributes. About a factor of 10 difference was observed in the wear rates of the materials. Although the behavior cannot be easily connected to any particular material property, in general, materials with multi-phase microstructure exhibited less wear than mono-phased materials.
