Effect of Temperature on Mechanical and Microstructural Properties of Hydroxyapatite-Alumina/Zirconia Nanocomposites
Abstract:   (9119 Views)
Two- step sintering (TSS) has been applied, in the present work, to suppress the accelerated grain growth of Hydroxyapatite Zirconia Alumina nanocomposites in the last sintering stage. The average grain size of near full dense specimens made via conventional sintering (CS) was around 400nm. By using novel tow- step sintering, however, the final grain size (200nm) dropped 2 times less than that for specimens produced by the CS method. After densification, the mechanical properties, the relative proportion of TCP formed and the microstructures of the composite were observed. By used of two step sintering, highest hardness and fracture toughness, lowest relative proportion of TCP and nanostructure were achieved.
Keywords: Tow-Step Sintering, Mechanical and Microstructural Properties, Hydroxyapatite-Alumina/Zirconia Nanocomposites.
