Here, τ is a constant that accounts for the initial scale thickness. Formation of the passive SiO2 layer explains the outstanding oxidation resistance of silicon-based ceramic. Oxygen transfer (diffuson) through the scale depends on temperature and pressure, however below 1400 °C it is independent on oxygen pressure. At higher temperatures though, permeation rates of oxygen are proportional to pressure.

摘要

Here, τ is a constant that accounts for the initial scale thickness. Formation of the passive SiO2 layer explains the outstanding oxidation resistance of silicon-based ceramic. Oxygen transfer (diffuson) through the scale depends on temperature and pressure, however below 1400 °C it is independent on oxygen pressure. At higher temperatures though, permeation rates of oxygen are proportional to pressure.
