Abstract
|
|
|
Purpose: This study was performed to compare sintering conditions for fabrication of porous Ti implant.
Methods: The porous Ti implant samples were fabricated by sintering of spherical Ti powders in vacuum and atmosphere conditions. Surface morphology, composition and phase were analyzed by FE-SEM, EDX and XRD.
Results: Sintered Ti implant in the vacuum consisted of particles connected in three dimensions by clear necking without excessive oxide layers. However, sintered Ti implant in atmosphere was formed excessive oxide layers with non-stoichiometric compounds.
Conclusion: The porous Ti implant can be sintered in vacuum condition preferably.
