PARTICULATE-REINFORCED TITANIUM COMPOSITES FOR ORTHOPAEDIC IMPLANTS

摘要：

In the present study,to enhance the strength of porous pure titanium scaffolds with high porosity,new particulate-reinforced Ti-based composites with the addition of biocompatible oxide particles such as TiO2,SiO2,ZrO2 and Nb2O5 were prepared using a powder metallurgical method.The strengths of the new particulate-reinforced titanium composites were found to be significantly higher than that of pure titanium with an excellent biocompatibility.SaOS-2 osteoblastlike cells grew and spread well on the surfaces of the new particulate-reinforced titanium composites.The present study illustrated the feasibility of using the particulate-reinforced titanium composites as an orthopaedic implant material.
