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.
