Nanotube (NT) surfaces generated on Ti alloys have garnered significant results in the medical field improving enhanced biocompatibility and excellent anti-corrosive properties. The work in question aimed to fabricate Ti nanotubes in different Ti alloys surfaces with excellent mechanical properties and subsequently evaluate their structural and surface properties. After the production of the nano surface, the materials were heated to promote the amorphous to crystalline structure transformation of the nanostructure. The alloys studied were commercially pure Ti (c.p-Ti), Ti-xNb (15, 40 wt %), and Ti-34Nb-6Sn. On the c.p-Ti nano surface, only rutile oxide was detected, while the other alloys exhibited a mixture of anatase and rutile crystal phase. The NT diameters varied depending on the substrate, following the trend: c.p-Ti > Ti-40Nb > Ti-15Nb > Ti-34Nb-6Sn. Similarly, surface roughness increased after annealing and followed the order: c.p-Ti > Ti-40Nb > Ti-34Nb-6Sn > Ti-15Nb. The contact angle values decreased significantly for all nanotubes surfaces and decreased more after annealing treatment being them: c.p-Ti > Ti-40Nb > Ti-34Nb-6Sn > Ti-15Nb.

摘要

Nanotube (NT) surfaces generated on Ti alloys have garnered significant results in the medical field improving enhanced biocompatibility and excellent anti-corrosive properties. The work in question aimed to fabricate Ti nanotubes in different Ti alloys surfaces with excellent mechanical properties and subsequently evaluate their structural and surface properties. After the production of the nano surface, the materials were heated to promote the amorphous to crystalline structure transformation of the nanostructure. The alloys studied were commercially pure Ti (c.p-Ti), Ti-xNb (15, 40 wt %), and Ti-34Nb-6Sn. On the c.p-Ti nano surface, only rutile oxide was detected, while the other alloys exhibited a mixture of anatase and rutile crystal phase. The NT diameters varied depending on the substrate, following the trend: c.p-Ti > Ti-40Nb > Ti-15Nb > Ti-34Nb-6Sn. Similarly, surface roughness increased after annealing and followed the order: c.p-Ti > Ti-40Nb > Ti-34Nb-6Sn > Ti-15Nb. The contact angle values decreased significantly for all nanotubes surfaces and decreased more after annealing treatment being them: c.p-Ti > Ti-40Nb > Ti-34Nb-6Sn > Ti-15Nb.
