Abstract
Modern gas turbine engines require superalloy components which have a combination of strength at high temperature and resistance to oxidation and sulfidation attack not obtainable with conventional alloys. These requirements are met by a composite of strong superalloy bodies protected with metallic diffusion coatings, formed by alloying the surface with aluminum and other elements.
Novel processing methods are frequently required to meet the needs of today's increasingly sophisticated applications. By working together, engine producers and coating vendors have been able to develop procedures to meet these needs.
