Wettability of Y₂O₃: A Relative Analysis of Thermally Oxidized, Reactively Sputtered and Template Assisted Nanostructured Coatings.

The wettability of reactively sputtered Y₂O₃, thermally oxidized Y-Y₂O₃ and Cd-CdO template assisted Y₂O coatings has been studied. The wettability of as-deposited Y₂O coatings was determined by contact angle measurements. The water contact angles for reactively sputtered, thermally oxidized and template assisted Y₂O nanostructured coatings were 99°, 117° and 155°, respectively.
