What causes the increased corrosion rate in high temperature environments?

AI Thread Summary
High temperature corrosion involves complex electro-chemical reactions that are significantly influenced by temperature. As temperature increases, the corrosion rate typically rises due to enhanced dissociation of reactants and increased diffusion of anions into the cation substrate. This elevated activity leads to more aggressive interactions between materials and corrosive agents, resulting in accelerated degradation. The mechanisms at play include changes in the stability of corrosion products and the mobility of ions, which contribute to the overall increase in corrosion rates at higher temperatures. Understanding these chemical processes is crucial for developing materials that can withstand extreme conditions.

Corrosion is a chemical (electro-chemical) reaction, and many or most increase with temperature, which may be related to disociation of reactants or diffusion of anions into the cation substrate.
