| Abstract Scope |
In this presentation, microstructural development and properties (to include both physical and mechanical) of Zirconia-Toughened-Alumina (ZTA) composite reinforced with 1 volume percent of magnesium oxide (MgO) / multi-walled carbon nanotubes (MWCNTs) and processed using the technique of spark plasma sintering will be highlighted. Specific details and role of processing parameters will be elaborated upon. The average grain size, density and micro-hardness was determined for the addition of magnesium oxide (MgO) reinforcement to the ZTA matrix. The highest fracture toughness was obtained by the addition of MWCNTs reinforcement to the ZTA matrix. Micro-hardness of the samples increased with the addition of MgO reinforcement to the ZTA matrix, while fracture toughness increased with the addition of MWCNTs to the ZTA matrix. The development of a material for use as a thermal barrier coating and also for its selection and use in dental applications will be presented and discussed. |
