High-temperature corrosion

<p>High-temperature corrosion is a mechanism of  <a href="/facts/Corrosion/lIC7H4we">corrosion</a> that takes place when <a href="/facts/Gas_turbine/JJJNwXrG">gas turbines</a>, <a href="/facts/Diesel_engine/9B9opxvA">diesel engines</a>, <a href="/facts/Industrial_furnace/Tl6Cr8Uy">furnaces</a> or other machinery come in contact with hot gas containing certain contaminants. Fuel sometimes contains <a href="/facts/Vanadium/UvKkKTSm">vanadium</a> compounds or sulfates, which can form low melting point compounds during combustion. These liquid melted salts are strongly corrosive to stainless steel and other alloys normally resistant with respect to corrosion at high temperatures. Other types of high-temperature corrosion include <a href="/facts/High-temperature_oxidation/2mI0zt7t">high-temperature oxidation</a>, sulfidation, and <a href="/facts/Carbonization/o8LenJPn">carbonization</a>. High temperature oxidation and other corrosion types are commonly modeled using the <a href="/facts/Deal-Grove_model/JW5xYedD">Deal-Grove model</a> to account for diffusion and reaction dynamics.
