Special problems are encountered in the use of gas turbine engines in salt atmospheres. Ingestion of salt in the presence of sulfur-containing fuels can cause sulfidation corrosion, and considerable effort has been devoted to the theoretical and experimental evaluation of this process. The authors’ company pioneered the development of laboratory testing procedures by which it became possible to study the sulfidation behavior of alloys. This paper reviews these studies, describing the apparatus, the tests, and their various effects.
