High-temperature Corrosion

Additionally, since high-temperature environments accelerate all corrosion processes, high-temperature corrosion can also change the microstructure of metals.

Specific examples of environments where high-temperature corrosion is induced are as follows:

• When oxygen reacts with a metal to form an oxide layer, it occurs in a combustion process or a high-temperature oxidation environment, such as in car engines or generators.
• When sulfur compounds generated from the combustion of petroleum products or coal react with a metal, such as in power plants or oil refineries.
• Salt from seawater causes corrosion in high-temperature environments, such as marine facilities and ships.
• Chlorine gas or chlorides can cause corrosion in high-temperature environments, such as those found in water treatment plants and chemical factories.

To suppress the occurrence of high-temperature corrosion under the conditions mentioned above, it is necessary to take appropriate measures according to each situation.
