The Effect of Hydroxyapatite Composition on β Titanium Nanocomposites
Abstract:
The effect of hydroxyapatite (HA) particle composition on the microstructure, Vickers microhardness, relative density and phases of β titanium nanocomposite prepared by powder metallurgy method were investigated experimentally. Hydroxyapatite particle in the range of 5 wt% to 25 wt% were mixed with Ti-35Nb-2.5Sn particles. The samples were pressed at 111 MPa and sintered at 900°C for 2 hours in a vacuum furnace. Result shows that by increasing the hydroxyapatite composition from 5 wt% to 15 wt %, the relative density and Vickers mirohardness increased. Phase analysis of raw materials was studied by XRD analysis and microstructure of composite by SEM.
