AC measurements and porous layer on titanium in methanolic 1M HCl

Abstract

Discusses the results of impedance measurements done for titanium metal in methanolic 1M HCl containing 0,1,3 and 5 volume per cent H2O. Titanium metal behaved actively in such solutions and became passive when a sufficient amount of water (5 per cent) was present. As a result of anodic oxidation a porous layer has been formed at the metal surface, characterized by the presence of an additional maximum in the phase angle curves. The radii of the pores were calculated from a kugel diffusion impedance element.
