Abstract
This work reports on the fabrication and thermal stability of self-organized titania nanostructures on Ti6Al4V alloy. Ti6Al4V sheets were anodized in 1 M NaH2PO4 containing 0.5 wt% HF. And the anodized sheets were heat-treated at different temperatures to test their thermal stability. SEM observations revealed that, for the two-phase Ti6Al4V alloy, there were two different kinds of nanostructures (nanotubes grown at alpha-phase region and inhomogeneous nanopores grown at beta-phase region) formed on the substrate surface. The nanotubes can withstand a high temperature of 650degC without collapsing but sinter to densification at 675-700degC.
