摘要: Abstract The biocompatibility of implants is largely determined by their surface characteristics. This study presents a novel method for performing electrochemical anodization on β-type Ti–25Nb–25Zr alloy with low elastic modulus (approximately 70 GPa). results in thin hybrid layer capable enhancing the characteristics implants. We investigated topography and microstructure resulting alloy. corrosion resistance was evaluated using potentiodynamic polarization curve measurements simulated body fluid. cytotoxicity according to International Organization Standardization 10993–5 specification. Cell adhesion human bone marrow mesenchymal stem cells test specimens observed scanning electron microscopy fluorescence microscopy. produced 40 nm-thick) oxide nanoporous outer sublayer (pore size
