Paper Title:
The Corrosion Behavior of Titanium in Hydrogen Peroxide Solution with Various Additives

The corrosion behavior of titanium in hydrogen peroxide solutions was studied by measuring the titanium ions concentration using spectrophotometer. The influence of additives (K+ , Ca2+ ,Na+ ,Mg2+ ,Cl- ,HPO4 2-, H2PO4 - ) on the corrosion behavior of titanium was examined. The results indicated that Ca2+ exhibited the highest inhibition to the titanium corrosion in hydrogen peroxide solutions, while HPO4 2- behaved as an accelerator to the corrosion. It was suggested that the Ca2+ was absorbed on the titanium surface to form a thin film of CaTiO3 or CaO2, and consequently, inhibited the corrosion of titanium. The acceleration of the titanium corrosion in the present of HPO4 2- was caused probably by the increased defect of surface oxide films after absorption of HPO4 2- ions.
