Resumo

O titânio é um elemento complexo e apresenta mais de uma forma cristalográfica, à temperatura ambiente apresenta uma estrutura cristalina hexagonal que se transforma em uma estrutura de corpo centrado à 800ºC, e um ponto de fusão de 1670ºC ± 5ºC. As ligas de titânio apresentam propriedades mecânicas superiores ao Ti c.p. além de excelente biocompatibilidade, característica que a torna material de escolha em aplicações ortopédicas e odontológicos. A liga usada neste estudo foi a liga Ti-6Al-4V ELI, obtida em formato cilíndrico, lixadas e posteriormente submetidas ao tratamento termoquímico com NaOH.  A caracterização físico-química foi realizada pelas técnicas de espectrometria de fluorescênica de raios X (XRF), microscopia eletrônica de varredura (MEV), difratometria de raios X (DRX) e espectroscopia de fotoelétrons excitados por raios X (XPS). Observou-se uma estrutura bifásica (α e β) e a formação de hidrogel de titanato alcalino (titanato de sódio (Na2Ti5O11)) sobre a superfície, devido a reação do filme de TiO2 com a solução NaOH. Conclui-se que com a imersão das amostras em NaOH resultando na cristalização da camada de hidrogel de titanato, pode favorecer a formação de fosfatos de cálcio, bem como a interação osso/implante.
