摘要: Abstract Surface mechanical attrition treatment (SMAT) was used to induce grain refinement on the surface of commercially pure Titanium (Ti). Pure nanocrystalline anatase thin film with nano pores deposited pre-SMATed Ti substrate via chemical oxidation by simply soaking in a mix solution 8.8 mol/l H 2 O and 0.1 mol/l HCl at 80 °C for 30 min followed heat 400 °C 1 h air. The nanoporous showed excellent bioactivity while being soaked simulated body fluid (SBF), which could be mainly attributed unique nanostructure SMATed surface. Mechanism formation titania also discussed.
