主 题：TiO2 nanotubes tribology titanium implant surface modification biomaterials
摘 要：TiO2 nanotubes(NTs)have a great potential in improving the osetointegration of titanium(Ti)-based *** efforts have been made to evaluate the biological performance of the TiO2 nanotube in regulating protein adsorption and cells *** often used in orthopaedic applications,although biotribological performance and biocorrosion are important issues in these applications,few researches have been reported on the biotribological perfonnance of NT *** paper reports the preparation of a structure-optimised TiO2 NT(SO-NT)material via a multi-step oxidation strategy,as well as its biotribological and biocorrosion *** this procedure,an interfacial bonding layer of approximately 120 nm=150 nm was first formed on the titanium substrate,which was then joined to the NT *** mechanical testing with respect to impact,bending,and biotribological perfbnnance have demonstrated the resultant SO-NT layer possess improved mechanical stability compared to conventional *** uniform hyperfine interfacial bonding layer with nano-sized grains exhibited a strong bonding to NT layer and Ti *** was observed that the layer not only effectively dissipates external impacts and shear stress but also acts as a good corrosion resistance barrier to prevent the Ti substrate from *** models were proposed to analyze and predict the shear performance and corrosion-resistance mechanisms of the resultant *** obtained results demonstrated that the SO-NT material has great potential in orthopaedic applications.
