The oxidation of metals in high temperature
WebbPilling and Bed worth proposed that oxidation resistance is related to the volume ratio of oxide and metal per grams atom of metal. The diffusion of either cation or oxygen ions usually controls the reaction rate of high-temperature metallic oxidation. WebbThe oxidation temperature influences the oxidation process and Fe2SiO4 morphology during the reheating process [7–9]. So far, some studies on the effects of the oxidation temperature on the oxidation mass gain and Fe2SiO4 have been reported. Suarez et al. [10] found that oxidation treatments in air at temperatures higher than 570 C lead to

Figure 1a shows the cross-section of an oxide scale formed on a low-alloy steel exposed to laboratory air at 550 °C for 72 hours.
WebbSingle-crystal spheres of tantalum were oxidized at 500°, 600°, 820°, and 925°C in an oxygen pressure of 450 torr. The oxidation rate is anisotropic at the higher temperatures with the {100} faces oxidizing slowest and the {110} faces fastest. However, at the lower temperatures the oxidation rate is apparently isotropic. The habit plane of the suboxide … Webbaccount this one.
