Summary

The dry friction and wear behavior of toughened zirconias against hardened steel was studied using the Falex ring and block technique. Three experimental ZrO2-Y2O3 ceramics and two commercial ZrO2-MgO ceramics were investigated. Each ceramic was tested at 500 and 2000 rpm at normal loads in the range 23 to 40.8 kg. Significant trends in the friction and wear data were found correlating composition, test speeds, and loads. Microstructural examination of the ring, ceramic block, and wear debris has shown that the wear process is very complex and incorporates a number of mechanisms.
