We report on a novel biocompatible hierarchical TiO 2 porous coating on the surface of Ti, processed via anodic oxidation. The coating consists of large (̃l-20 μm) pores on the microscale and nanotubes (̃50 nm diameter) on the nanoscale. This structure is exciting because of its potential application as a bioactive coating for Ti bone implants. Surface characterization of the coating showed nanotubes of relatively uniform diameter. The interface between TiO 2 nanotubes and Ti, studied by transmission electron microscopy, was incoherent. The tubes were also somewhat interconnected.
