Resumen

This study introduces the anisotropy efect of Ti6Al4V substrate obtained by electron beam melting (PBF-EB) on the anodizing process, revealing its capacity to induce anisotropic TiO2 nanotubes. Highly organized TiO2 nanotubes are formed on Ti6Al4V substrates produced through PBF-EB or forging, with the PBF-EB cross-orientation displaying superior nanotube growth due to enhanced catalytic activity. Morphological and electrochemical characterizations underscore the signifcant infuence of substrate orientation and anodizing voltage on nanotube growth and corrosion resistance. PBF-EB-cross orientation at 30 V exhibits a thicker and more homogeneous nanotube layer, resulting in improved flm resistance and substantially lower corrosion rates compared to forged substrates. The electrochemically calculated nanotube flm thickness aligns with microscopic analyses, emphasizing the importance of a homogenous and resistive nanotube coating for efective corrosion control
