摘要

Ti-Al-Zr alloy has been oxidized at 360°C in alkaline steam at a pressure of 10.3 ± 0.7 MPa. Cross-sectional transmission electron microscopy (TEM) observations indicated that the oxide scale of Ti-Al-Zr alloy was composed of outer and inner subscales, in which the outer layer consists of anatase-TiO₂ and the inner layer a mixture of TiO and Ti ₂O. The thickness of the Ti₂O, TiO and anatase-TiO ₂ were approximately 50, 100 and 400 nm, respectively. These results were confirmed by X-ray energy dispersive spectrometry (EDS) measurements. The enhanced corrosion of titanium alloys in LiOH solution is attributed to a high hexagonal Ti₂O to tetragonal TiO₂ phase transformation rate induced by the substitution of Li⁺ for Ti⁴⁺ in the oxide layer.
