Abstract:In order to introduce a so-called reactive element simultaneously at all the surfaces of a NiCr (Ni-20wt.%Cr-1.5wt.%Si) metallic substrate alloy, an easy to apply surface treatment was used: an yttrium containing thin film (constituted of a hydrated yttrium hydroxide nitrate) was electrodeposited from a mixed water-ethanol solution. After a thermal conversion treatment at 600 C under argon, leading to an Y 2 O 3 coating, specimens were submitted to high-temperature oxidation testing, under artificial air at at… 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.
