Surface Microstructure and Performance of Anodized TZ30 Alloy in SBF Solution

Anodization is performed on the Ti-30Zr-5Al-3V (TZ30) alloy to improve its surface performance. X-ray diffractometer (XRD), scanning electron microscopy (SEM), and Olympus microscope are used determine phase constitution, morphology, thickness of anodization film (AOF). Tribological tests electrochemical corrosion experiments carried out measure, respectively, wear behavior resistance AOFs in simulated body fluid (SBF) solution. The microstructure characteristic AOF anodized at low voltage (20 V) composed compact loose regions. As applied increases 60 V, regions transform progressively into regions, then grow nanotube Besides, an increase from 8.6 ± 4.61 ?m 20.7 2.18 ?m, a gradual microhardness 364.6 14.4 HV 818.4 19.3 HV, also exhibited as 20 V V. Specimens 40 have friction coefficient (~0.15) rate (~2.2 mg/N/m) SBF enhanced wearability originates high hardness various mechanisms. Potentiodynamic polarization curves suggest that solution all specimens greatly improved, thanks protection TiO2 film.
