Abstract

In the present investigation, the mechanical properties of TiNb alloys were modified by electrochemical treatment. The properties of the TiNb alloy specimens were determined by electrochemical measurement and material analyses. The effects of titanium hydride compounds on the formation of porous structural oxide film during electrochemical surface treatment are examined by XPS, TF-XRD and SEM. Oxide films are formed during anodization following cathodic pretreatments, TiH1.971 is formed by cathodic pretreatment. The TiH1.971is directly dissolved following anodic treatment. Additionally, the porous TiNb that was formed by the dissolution of TiH 1.971 were modified to porous oxide films. Hydrogen charging is important in forming porous oxide films. Anodization following cathodic pretreatment not only yields a thick oxide film, but also produces porous structures, Implanting bioactive TiNb into a porous oxidation film promotes bone-interface contact, improving osseo/osetointegration. copyright The Electrochemical Society.
