Abstract:Analytical and experimental research was conducted to evaluate a ceramic seal system for a high-pressure turbine employing plasma-sprayed graded metallic ceramic, yttria-stabilized zirconium oxide (YSZ). The performance characteristics of several YSZ configurations were determined through rig testing for thermal shock resistance, abradability and erosion resistance. Results and test data acquired from this work indicate that this type of sealing system offers the potential to meet the operating requirements of… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
