Abstract

Anodizing of Al-Ti alloys, containing 3, 12, 15, 30 and 45at.%Ti, is examined at 5mAcm -2 in 1moldm -3 sulphuric acid at 293K. Porous films are formed up to 15at.%Ti, with titanium increasing the anodizing voltage and pore size. In contrast, a barrier-type film is formed at 30at.%Ti, with a finely porous outer region, while at 45at.%Ti, barrier-type film growth is accompanied by oxygen generation. Ti:Al atomic ratios in the films are similar to those in the respective alloys. Reduced levels of sulphur occur in barrier-type films compared with porous films. © 2011 Elsevier Ltd.
