The effect of dolomite addition onto the phases and hardness of zirconia toughened alumina

Zirconia toughened alumina (ZTA) is one of the composite ceramics that are widely use in load bearing and wear resistant applications. The composite is known for their good hardness and toughness, due to the presence of both Al2O3 and yttria stabilized zirconia (YSZ). The enhance toughness for ZTA...
