 The nanoporous or nanotubular complex oxide layers were developed on high-fraction beta-phase quaternary TNBZR TA and TNBZR FA promising biomedical alloys with a low elasticity modulus. Surface modification was achieved by electrochemical anodization aimed at the synthesis of the morphology of the nanostructures, which exhibited inner diameters of 15 to 100 nanometers. Scanning electron microscopy, SEM, energy dispersive spectroscopy, EDS, X-ray diffraction, XRD, and current evolution analysis were performed for the characterization of the oxide layers. By optimizing the process parameters of electrochemical anodization, complex oxide layers with pores or tubes opening of 18 to 92 nanometers on T, 10 NB, 10 ZR, 5 TA, 19 to 89 nanometers on T, 20 NB, 20 ZR, 4 TA, and 17 to 72 nanometers on T, 29.3 NB, 13.6 Z.
