The Anatase Formation on Anodised Titanium in Sulphuric Acid

Abstract:

Anodic oxidation is used to evaluate the effects of pure titanium in a sulphuric acid electrolyte in order to evaluate the relationship between the TiO₂ anatase crystalline phase formation and anodisation parameters. Multiple characterisation techniques were used and found that the thickness showed significant increase in TiO₂ at 70V, FESEM observed significant porosity at the arcing voltage commencement (100V). XRD analysis observed anatase peak threshold at 70V, However Raman Microscopy showed anatase significance formation between 20V-30V. We conclude that anatase presents at low voltage 20-30V while rutile peaks increase initially (100V and 150V) and the amount and /or crystallinity of anatase are/is influenced by the applied voltage.
