Abstract:Yttria stabilized zirconia (YSZ) particle suspension in acetylacetone (ACAC) was deposited onto Fecralloy substrates by using EPD and then constrained sintered at 1200°C. Before EPD, the operational pH value of the suspension was adjusted with addition of acetic acid or base triethanolamine (TEA). The effect of suspension pH on the deposition of EPD coatings was studied with respect to the suspension stability, coating density and microstructure. Results showed that the zeta potential decreased to close to zer… Show more
scite is a Brooklyn-based startup 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 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.
