Characterization of Long-Term Corrosion Performance of TI15MO Alloy in Saline Solution
Abstract
The Ti15Mo alloy has been studied towards long-term corrosionperformance in saline solution at 37°C using electrochemical impedancespectroscopy. The physical and chemical characterization of the materialwere also investigated. The as-received Ti15Mo alloy exhibits a singleβ-phase structure. The thickness of single-layer structured oxidepresented on its surface is ~4 nm. Impedance measurements revealed thatthe Ti15Mo alloy is characterized by spontaneous passivation in thesolution containing chloride ions and formation of a double-layerstructured oxide composed of a dense interlayer being the barrier layeragainst corrosion and porous outer layer. The thickness of this oxidelayer, estimated based on the impedance data increases up to ~6 nmduring 78 days of exposure. The observed fall in value of the log|Z|f =0.01 Hz indicates a decrease in pitting corrosion resistance of Ti15Moalloy in saline solution along with the immersion time. The detailed EISstudy on the kinetics and mechanism of corrosion process and thecapacitive behavior of the Ti15Mo electrode | passive layer | salinesolution system was based on the concept of equivalent electricalcircuit with respect to the physical meaning of the applied circuitelements. Potentiodynamic studies up to 9 V vs. SCE and SEM analysisshow no presence of pitting corrosion what indicates that the Ti15Moalloy is promising biomaterial to long-term medical applications.
