Paper Title:
On Studying Surface and Nanomechanical Properties of Ti-O Films by Alkali Treatment
  Abstract

Titanium oxide (Ti-O) films have been widely used in the fields of electron, photology and medicine due to its distinctive optical, electrical and chemical properties. In this paper, Ti-O films were synthesized by micro-arc oxidation firstly, and then surface was modified by NaOH alkali solution under different treatment time. The wettabilities of as-prepared films were investigated by contact angle measurements using four common liquids. nanoindentation was adopted to obtain the films’ nanohardness and modulus. The results show that Ti-O films tend towards hydrophilia and its surface energy increased after alkali treatment, but no obvious effects to nanohardness and modulus of Ti-O films. Surface roughness of Ti-O films increases after alkali treatment firstly, but decreased with continuing to increasing the times of alkali treatment.
