Properties Of Composites

Bovine derived hydroxyapatite was doped with partially stabilized zirconia with 3 mol% yttria. The influence of sintering temperature and the amount of the incorporated zirconia on densification, mechanical properties, crystalline structure and microstructure was investigated. The results indicate that the produced materials exhibit poorer mechanical properties than the relevant composite materials of enamel derived hydroxyapatite. This difference can be attributed to F, since F-content in bone is much higher than in enamel. Hence, in the light of the prospective use of the investigated materials in biomedicine, bovine derived hydroxyapatite doped with zirconia can potentially serve as graft material for load bearing applications if very small amount of F can be incorporated, in order to resemble the composition of enamel derived apatite.

Structural Applications

Zirconia has attracted considerable interest for structural applications because of its high fracture strength and fracture toughness. Polycrystalline alumina (PCA) chopped fiber (10 vol. %)-reinforced yttria partially-stabilized zirconia (Y-PSZ) composites have been fabricated by hot pressing at 1550°C and 2200 psi under vacuum atmosphere. The microstructure of the matrix, fiber, and matrix/fiber interface of the composites was characterized using transmission electron microscopy in order to correlate the microstructural and mechanical properties. Cross-sectional TEM samples were prepared by mechanical grinding, dimpling, and ion-milling. The samples were analyzed using a Philips EM400T TEM and a Noran ultrathin window Micro-Z detector. Selected area diffraction (SAD) and energy dispersive X-ray spectroscopy (EDXS) were used to identify the microstructure and microchemistry of the composites, respectively. The mechanical properties of the composites at room temperature were obtained using four-point bending tests. Creep tests were conducted by four-point bending at 1100°C and compressive stress of 46.3 MPa for 24 hours in air.
