Polarization Measurements on Titanium Tube and Sheet Having Preferred Orientation Textures

Abstract
The influence of preferred orientation texture on the anodic polarization behavior of titanium tubing and sheet has been investigated. Potentiostatic polarization measurements were made on specimens in the annealed and deformed conditions during exposure to boiling NaCl solutions (pH=1) and to 1N H2SO4 (pH=0.3) solutions at 23 C (73 F). Results were correlated with single crystal data, and it was found that basal (0001) orientation texture has a marked effect on the anodic polarization of titanium, especially in the active region where this texture gives lower current densities. Polarization curves and examoles of the microstructures are shown and discussed.
