Title: Development of nondestructive evaluation methods for ceramic coatings.

Abstract

Various nondestructive evaluation (NDE) technologies are being developed to advance the knowledge of ceramic coatings for components in the hot gas-path of advanced, low-emission gas-fired turbine engines. The ceramic coating systems being studied by NDE include thermal barrier coatings (TBCs) and environmental barrier coatings (EBCs). TBCs are under development for vanes, blades and combustor liners to allow hotter gas path temperatures and EBCs are under development to reduce environmental damage to high temperature components made of ceramic matrix composites (CMCs). Data provided by NDE methods will be used to: (a) provide data to assess reliability of new coating application processes, (b) identify defective components that could cause unscheduled outages (c) track growth rates of defects during use in engines and (d) allow rational judgement for replace/repair/re-use decisions of components.
