Sulfidation attack, the accelerated oxidation of gas turbine components, occur when the surfaces are covered with a fused alkali salt. Oxide ions present in the melt, react with and render the normally protective oxide scale ineffectual allowing the salt to oxidize the substrate. Turbogard™, a chromium containing fuel additive, attenuates sulfidation corrosion. Turbogard reacts with and alters the oxide ion content of the corrosive melt. Even in the presence of corrosive lead deposits, hot corrosion attenuation was observed.
