dióxido de titânio, anodização, Ti6Al4V, implantes, difração de raios-XResumo
Um dos grandes desafios na área de biomateriais é desenvolver implantes que consigam aliar biocompatibilidade e resistência à corrosão. Ligas de titânio vêm sendo largamente aplicadas com essa finalidade, uma vez que apresentam tais características, além de exibirem maior resistência mecânica e melhor custo-benefício frente ao titânio puro. Sob essa perspectiva, este trabalho estudou as condições do processo de anodização da liga Ti6Al4V. A caracterização do óxido formado foi realizada por microscopia eletrônica de varredura (MEV) acoplado a uma sonda de espectroscopia dispersiva em energia (EDS) e difração de raios-X (DRX). Os resultados indicam que apenas o H2SO4 favoreceu a formação de filmes cristalinos, contudo, em H3PO4, os filmes são enriquecidos com fósforo.
