This article provides an overview of key thermal spray coatings used in compressors, combustors, and turbine sections of a power-generation gas turbine. It describes the critical components, including combustors, transition ducts, inlet nozzle guide vanes, and first-stage rotating airfoils. Design requirements are reviewed and compared between aerospace and power generation coatings. Application process improvement areas are also discussed as a method of reducing component cost.
