Abstract
We report for the first time on mechanical properties of anodically formed, self-organized TiO2 nanotube layers on titanium. We compare their behavior in their virgin state and after conversion to their semi-metallic form by an acetylene treatment. We show that the acetylene treatment leads to significant enhanced hardness, tensile strength and friction behavior. (C) 2010 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
