Abstract
The hierarchical micro-nanostructure has been proved to endow titanium (Ti) surface with good biological properties. However, to achieve satisfied osseointegration, good corrosion resistance and mechanical properties are also necessary. Therefore, in this paper, the corrosion resistance and mechanical properties of the Ti implant with hierarchical micro-nanostructure were investigated. The corrosion resistance was detected by polarization curve test, and the mechanical properties were evaluated by friction-wear experiment and nano indentation test. The results showed that the micro-nanostructured Ti surface showed increased corrosion potential, and it also showed decreased friction coefficient, stiffness and Young´s modulus, similar to that of the cortical bone. The improved corrosion resistance and mechanical properties might endow the micro-nanostructured Ti implant with good osseointegration and promising application in clinic.
