Electrochemical and stress corrosion cracking behaviour of titanium in n-propanol and iso-propanol solutions

Titanium shows severe localised corrosion in non-aqueous media in the presence of applied stress and crevice. The present work brings a contribution to the behaviour of Ti in non-aqueous media by studying the role of water on the electrochemical properties and stress corrosion cracking (SCC) sensitivity of Ti in n-propanol and iso-propanol solutions. The anodic behaviour of titanium in n-propanol–H2O and iso-propanol–H2O systems is quite similar to that observed in methanol–H2O and ethanol–H2O systems.
