The hot corrosion of single crystal and polycrystalline aluminas has been investigated in SO2–SO3–O2 environments and in the presence of molten Na2SO4-based deposits at temperatures of 700 and 1000 °C. The effect of microstructure and impurities on the corrosion has been emphasized.

The high‐temperature corrosion of bulk silica glass was studied in pure oxygen and in SO 3 ‐containing oxygen atmospheres in the presence of liquid sulfate deposits at temperatures of 700° and 1000°C. No reaction and devitrification were observed without Na 2

The oxidation and hot corrosion behavior of the binary iron aluminide, Fe-25Al (at.%), has been studied at 1100 K, 1225 K and 1330 K. Hot corrosion studies were conducted by coating the specimen surfaces with 2.5 ± 0.2 mg/cm2 of Na2SO4 prior to exposure in pure oxygen. Parabolic rate constants were obtained from weight gain data. The faster kinetics in

Microcell processes in hot corrosion
Corrosion Science, 1993Abstract It has been proved that there exists a microcell process in hot corrosion. The microcell is mainly determined by inhomogeneities and defect properties in the oxide film formed on the surface of the metal or alloy during hot corrosion. Three experimental methods have been used to prove the above mechanism.

Hot corrosion in a temperature gradient
Materials and Corrosion, 1999Abstract Hot corrosion is the accelerated attack of materials at elevated temperatures that is induced by a thin film of fused salt. Many materials that experience hot corrosion are exposed to high heat fluxes and temperature gradients. The hot corrosion of metals can be described by the dissolution of a protective metal oxide into the ...
