Anodic Behaviour of Titanium-12 in 0.1 M Ferrous Ammonium Sulphate under Different Anodizing Conditions


Anodization of Titanium-12 alloy has been studied in aqueous ferrous ammonium sulphate electrolyte at different current densities, temperatures and electrolyte concentrations under galvanostatic conditions. The surface morphology of the anodic films formed were studied by using Scanning Electron Microscopy. From the plots of formation voltage vs. time, the rates of film formation were calculated. Kinetics of film formation was studied in aqueous ferrous ammonium sulphate electrolyte of different concentrations ranging from 0.1 M to 0.00625 M and at different temperatures ranging from 310 K to 350 K under galvanostatic conditions. It was also studied the anodization at different current densities ranging from 4 to 64 From the results it was found that the rate of film formation and breakdown voltage decrease with decrease in electrolyte concentration and increase in temperature. But they increase with increase in constant current density. It has also been observed the significant change in film surface morphology from SEM studies at different anodizing conditions.
