【Basic Knowledge 22】What is high-temperature oxidation? (Questionnaire with Prizes)
Thread Content
Please explain what high-temperature oxidation is The process in which metals form metal oxides through oxidation with their surrounding environment at high temperatures. Carbon steel develops an oxide film at air temperatures of 200–300°C, and the oxidation rate increases significantly at 800–900°C
The volume percentage of oxygen in the air is 21%; many substances undergo oxidation reactions in air, and an increase in temperature accelerates the rate of these reactions. High-temperature oxidation refers to oxidation reactions that take place under high-temperature conditions
What is high-temperature oxidation? High-temperature oxidation is a type of metal corrosion that occurs when a metal material reacts with oxygen at high temperatures to form oxides.
React with oxidizing substances under high-temperature conditions
A type of metal corrosion that occurs at high temperatures when metal materials react with oxygen to form oxides. Broadly defined, high-temperature oxidation includes sulfidation, halidation, nitridation, carburization, etc
What is high-temperature oxidation? A type of metal corrosion that occurs at high temperatures when metal materials react with oxygen to form oxides. Broadly defined, high-temperature oxidation includes sulfidation, halidation, nitridation, carburization, etc. During the high-temperature oxidation of metals, it is only possible to protect the metal by forming a complete, dense oxide film that adheres well to the metal matrix. The main theory for the high-temperature oxidation of metals is Wagner’s oxidation theory; according to this theory, the thickening of the oxide film follows a parabolic relationship with the oxidation time. The high-temperature oxidation rate of metals is primarily controlled by factors such as the type and concentration of defects in the oxide film, the ratio of the volume of the oxide film to the volume of metal consumed, and the stress within the oxide film.

At high temperatures, certain elements in steel are oxidized, resulting in a decrease in its mechanical properties.
