Anodic and cathodic polarization behavior of Ti--6Al-4V alloy were determined by potentiostatic and galvanostatic techniques in deaerated 1, 5, and 10N sulfuric acid solutions. In the active region, metallurgical processing, which included cold rolling and thermal treatment, had no effect on the corrosion behavior. It is suggestcd that a titanium hydride film exists on the titanium alloy surface. In the passive region, plastic deformation, due to cold rolling, did increase the passive current density; whereas crystallographic texturing did not have an effect. The introduction of an alpha -phase due to thermal treatment produced an additional pcak in the passive region. (auth)
