Factors Controlling the Corrosion Behavior of Titanium and Titanium-Nickel Alloys in Saline Solutions Available to Purchase

The corrosion behavior of Ti in boiling acidic chloride solutions has been evaluated with regard to the nickel ion content of the corroding environment and the detailed crystallographic structure of the metal. Also, some experiments on the corrosion behavior of various Ti-Ni alloys are outlined. It has been found that the corrosion behavior of Ti is strongly anisotropic, minimum corrosion occurring on the basal plane. Further, the presence of a small quantity of Ni, either in the alloy or in the environment, markedly enhances the corrosion resistance of Ti.
