Abstract

The purpose of this study was to test in-vitro the micro and nano tribological properties of Y-TZP (Yttria Tetragonal Zirconia Polycrystalline) material used in the construction of artificial teeth or dental crowns. The results showed that the effect of pH was to accelerate the wear rate of the Y-TZP material. However, this phenomenon was more apparent in acid than in alkaline environments. Wear maps were constructed based on the results identifying wastage regimes for the material in the erosion-corrosion conditions at a range of impact angles. In addition, a wear map was generated based on the transition from tetragonal to monoclininc phase for the material and the transition to high wear at various pHs and exposure times.
