Li, Yuncang, Hodgson, P.D. and Wen, C. 2011, Particulate-reinforced titanium composites for orthopaedic implants, in ICHMM 2011 : Advances in heterogeneous material mechanics 2011 : proceedings of the Third International Conference on Heterogeneous Material Mechanics : May 22-26, 2011, Shanghai, China, Destech Publications, Lancaster, Pa., pp. 1131-1135.
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 osteoblast-like 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.
