WebFeb 26, 2024 · At high temperature, the density of the Al 2 O 3 layer was insufficient, and Ti continued to oxidize. At the same time, the O 2 partial pressure at the interface between the matrix and the oxide film was reduced, thus low-valent titanium oxides are formed. 4. … WebOct 15, 2024 · After oxidation for 2 h, the scale thickened with many holes. When the oxidation time is 100 h, a relatively continuous scale formed. Moreover, a MoO 2 middle layer and an interlayer composed of Mo ss and SiO 2 also appeared below the scale, as being presented in Figure 1 f–h.
WebA comparative EDS analysis shows that porous surfaces oxidized at higher temperatures have higher oxygen-to-silicon ratios. Our results indicate that the chemoresistive response due to the presence of isopropanol vapors at room temperature also increases with an increasing oxidation temperature.
