Abstract

At elevated temperatures hot corrosion often takes place in gas turbines and other combustion turbomachinery. The main corrosion issues are high-temperature environmental attack in the form of high-temperature oxidation and hot corrosion. Two case histories of gas turbine hot components are presented. The mechanisms for different types of hot corrosion are discussed. The influence of temperature, composition, and microstructure of materials on hot corrosion is described. A variety of practical approaches to minimize hot corrosion are considered.
