Influence of microstructural features on the growth of nanotubular oxide layers on β-phase Ti-24Nb-4Zr-8Sn and α + β-phase Ti-13Nb-13Zr alloys
Abstract
Anodization of titanium alloys allows us to obtain nanotube oxide structures consisting of a mixture of oxides ofalloying additives which might extend their scope of application and improve their surface properties. However,the complex microstructure of two-phase α + β Ti alloys presents a much greater influence on the homogeneity ofnanotubular layers as compared to a single α-phase pure titanium. In this work, we analyzed how changes at themicrostructural level (the amount, size or shape of the precipitates of individual phases) affect the growth ofnanotubes on two biomedical alloys Ti-24Nb-4Zr-8Sn and Ti-13Nb-13Zr after different heat treatment. We foundthat morphology of nanotubular oxide layer imitate the microstructure of the substrate quite accurately what hasbeen clearly seen especially for Ti-13Nb-13Zr alloy with a different size and morphology of α/α’ phase precipitates.The height of nanotubes was highly dependent on the β phase content, i.e. the higher the amount of theβ phase, the higher the oxide nanotubes what is presumably due to the preferential growth of Nb2O5 and ZrO2oxides. Moreover, the results showed that it is possible to fabricate crystalline nanotubes on the annealed Ti-13Nb-13Zr substrates immediately after the anodization process without a typical post-heat treatment. Wesuppose that this results from the presence of crystalline transition layer after initial heat treatment as well asinternal stresses in the two-phase microstructure that induced the crystalline transformation.
