Surface characterization and corrosion behavior of thermally oxidized Ti-15Mo alloy for dental implant applications |
| 초록 |
Surface modification of titanium and its alloys are increasingly studied to improve mechanical properties and corrosion resistance on dental implants involving Ti-Mo alloys. The present study was to evaluate the surface characteristics and corrosion behavior of thermally oxidized (TO) Ti-15Mo alloy. TO of Ti-15Mo alloy at 500, 650 and 800oC for 8, 16, 24 and 48h. The surface characteristics of Ti-15Mo alloy with and without thermal oxidation treatment were characterized by field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), surface roughness test, and potentiodynamic polarization test in Ringer’s solution. The surface morphology of thermally oxidized Ti-15Mo alloy reveals the formation of a thin oxide layer at 500oC that changes into a small grain structure at 650oC and complete coverage of larger grain structure at 800oC. The phase constituents of the oxide film formed during thermal oxidation exhibit a strong dependence on the treatment time. TO of Ti-15Mo alloy offers excellent corrosion resistance in Ringer’s solution when compared to pure Ti and untreated Ti alloy. TO of Ti-15Mo alloy can be used as a suitable alternative material for dental implant application.
