Sulfidation And Its Inhibition In Turbomachinery
United Technologies Research Center has carefully investigated the detailed mechanisms of gas turbine sulfidation and its inhibitions. Sulfidation, the salt accelerated oxidation of superalloys, is addressed in terms of the relationships between fuel and combustion air contamination, turbine deposit composition, alloy composition, and metal temperature. Superalloy oxidation kinetics and deposit electrochemical data is presented to substantiate that oxide ion-initiated and sustained attack to the normally protective oxide scale is responsible for hot corrosion. Application of this mechanism to field experience is made to explain corrosion performance.
