Abstract:Nowadays, the selection of a suitable spray method to design the coating microstructure such as its porosity, is key to effectively improving the properties of the base materials. In this study, the microstructures and thermal insulation capability of chelate flame-sprayed erbium oxide (Er2O3) and yttrium oxide (Y2O3) coatings directly deposited on aluminum alloy (A5052) substrates were investigated. A rotation apparatus and cooling agent (liquid nitrogen) were used during the synthesis to cool the substrate a… 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.
