Pure Titanium Corrosion inhibition by heat treatment in 3M HCl solution: An Electrochemical Impedance Spectroscopy (E.I.S) study

Grain structure orientational change in Ti6Al4V alloys induced by sea water quenching and novel stress relief annealing process

“…This α↔β phase transition temperature can be altered by impurities, alloying as well as deformations processes [7,8]. Quenching from high temperatures and annealing of commercial pure (CP) Ti result in improved corrosion properties by rearranging grains in a precise direction [9]. The multiple steps involving high-temperature cycles during heat treatment may result in a mixture of crystal orientations and yield mechanical properties, which are different from the original processing [10].…”

Corrosion Resistance of Industrial Pure Titanium and its Alloys under High Temperature and Different Cooling Methods

“…At present, corrosion studies of pure titanium mainly focus on neutral and sour solution at room temperature. Hida et al [1] discussed the electrochemical impedance spectroscopy (EIS) of pure titanium in 3M-HCl solution after heat treatment, and concluded that the corrosion resistance of pure titanium after heat treatment in 3M-HCl solution is improved. On account of improving anti-corrosion of pure titanium, alloying may be an effective way to increase the corrosion resistance of titanium in some extremely corrosive media such as hydrochloric acid, nitric acid and sulfuric acid [2,3].Tamilselvi et al [4] used EIS to study the effect of potential on the electrochemical behavior of pure titanium, Ti-6Al-7Nb and Ti-6Al-4V ELI alloys under brine conditions.…”
