Surface Treatment to Improve Corrosion Resistance of Pure Titanium

The corrosion behaviors of pure titanium UNS R50250 and UNS R50400 were investigated and compared with electrochemical behavior of Ti-0.2Pd and Ti-0.3Mo-0.8Ni alloys (UNS R52400 and UNS R53400 respectively).

Titanium has an outstanding corrosion resistance due to the thin oxide protective layer (max 10 nm) that is formed spontaneously on its surface when exposed to aerated environment which allow using titanium in severe working condition such as offshore (up to 260°C) acid environment aerospace automotive high temperature chemical & food industry. Nevertheless commercially pure titanium may suffer localized corrosion in hot salty water ads well as acidic corrosion in fluoride containing solution or hydrogen embrittlement.Surface treatments specifically anodic oxidation has been considered to tune the TiO2 layer in order to increase its thickness and to obtain a mostly amorphous phase with the final aim to improve titanium corrosion resistance in highly aggressive environment.

Key words: Titanium, anodic oxide, corrosion, pitting.
