Abstract:The possibility of extending the service life of the high pressure hardware for gas turbine engines using a novel repair procedure was evaluated in a laboratory study. In the laboratory simulation, both high and low activity platinum aluminide overcoatings of a partially stripped platinum aluminide were evaluated and contrasted. The results indicate that a chemically homogenous, relatively uniform thickness, platinum modified coating can be formed by low activity aluminizing on a substrate with surface areas o… 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.
