Abstract

The effect of microscale residual stresses on the initial corrosion behavior of Ti35 alloys in boiling nitric acid solutions was investigated using a combination of electrochemical and immersion tests. The concentration of microscale residual stresses 48 h before corrosion accelerated the dissolution of Ti²⁺, Ti³⁺, and Ta⁵⁺, as determined by electrochemical impedance spectroscopy measurements and quantitative X-ray photoelectron spectroscopy analysis. After 48 h, the formation of oxide films with consistent compositions and contents (TiO₂-51%, Ti₂O₃-47%, and Ta₂O₅-1.9%) prevented the corrosion medium from reaching the outer surface of the metal matrix, reducing the effect of residual stresses on the corrosion behavior.
