Hot Corrosion of Metals and Alloys
Oxidation of Metals, 2011When metals and alloys are used at high temperatures, especially in combustion processes, deposits often accumulate on the metal surfaces and affect the oxidation processes. This paper is concerned with deposit-induced accelerated corrosion, or hot corrosion, of metals and alloys.

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

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 ...

Titanium Corrosion by a Hot Perfluoropolyether
Corrosion, 1980The kinetics and mechanism of titanium corrosion by Krytox MLO-71-6 are reported. The rate of corrosion is found to be dependent on the presence of molecular oxygen in the environment. For titanium corrosion to occur, the lubricant chains must first break down into smaller reactive molecules.
