Influence of Texture on the Corrosion and Film Formation of a Titanium Single Crystal

Recently, it has been shown that the detailed crystallographic structure, or texture, of titanium has a marked influence on its corrosion rate in acidic solutions. For example, Ruff and Fraker¹  have demonstrated that the corrosion of titanium in sulfuric acid environments is a minimum on the basal {0001} plane. In addition, it has now been shown²  that the preferred basal texture in certain fabricated products, e.g. extruded titanium tubing which on average contains a 2.5 times random basal texture,²  does result in improved corrosion resistance.

Green and Latanision³  also have shown that the basal {0001} plane of titanium remains passive, while other low index faces such as the prism ${101¯0}$⁠, second order prism ${112¯0}$⁠, and pyramidal ${112¯2}$ become active in boiling acidic chlorides likely to be encountered...
