✦ Synopsis

The galvanostatic anodization of commercially pure titanium is studied with current densities lower than 500 Am -' in I M sulphuric acid between 25 and 75°C . Two types of electrochemical behaviour are observed: the first type is characterized by a maximum value of the cell voltage and the second one by a continuous increase of the anode to cathode (which is platinum) potential difference . These different behaviours may be related to different structures of the anodic films (as observed by SEM and TEM) and to the compositions of these films (as determined by Auger analysis, RHEED and HEED) .
