Abstract

Titanium has been used as an important implant material in humans, and it is important to investigate the interaction between titanium and H₂O₂ produced from the inflammatory response during the implantation procedure. However, the reports about the interaction between H₂O₂ and nanostructured or ultrafine-grained Ti are still very limited. In this work, the interaction between H₂O₂ and bulk Ti with a nanostructure surface was reported. At first, a commercial pure Ti plate underwent a surface mechanical attrition treatment (SMAT) in vacuum for 1 h to produce a nanocrystalline layer of Ti about 30 μm thick. Then the SMAT Ti was immersed into hydrogen peroxide solution for 24 h at 25 °C, and nanoporous titania was produced on the SMAT Ti surface. The nanoporous structure could be retained even after calcinations at 600 °C, while only intergranular corrosion appeared in coarse-grained Ti after the same chemical treatment. © 2006 Elsevier B.V.
