What causes the increased corrosion rate in high temperature environments?

Click For Summary
SUMMARY

The discussion focuses on the chemistry behind high temperature corrosion and its increased rate in such environments. It is established that corrosion is primarily a chemical (electro-chemical) reaction, with rates typically increasing with temperature. This increase is attributed to the dissociation of reactants and the enhanced diffusion of anions into the cation substrate. Understanding these mechanisms is crucial for mitigating corrosion in high temperature applications.

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.
