In this paper, Ti-Zr(10, 20, 30 and 40 wt%) alloys were prepared by arc melting and nano-structure controlled for 24 hr at 1000 °C in argon atmosphere. Formation of oxide nanotubes are conducted by anodizing a Ti-Zr alloy in H3PO4 electrolytes with small amounts of fluoride ions at room temperature. The corrosion properties of the specimens were examined through potentiodynamic test (potential range of -1500 ~ 2000 mV) in 0.9% NaCl solution by potentiostat (EG&G Co, PARSTAT 2273. USA). Microstructures of the alloys were examined by optical microscopy (OM), scanning electron microscopy (SEM), x-ray photoelectron spectroscopy (XPS) and x-ray diffracto-meter (XRD).
