NANOSTRUCTURED YSZ COATINGS ON TITANIUM

Abstract

An approach providing yttrium-stabilized zirconia coatings deposition on titanium is suggested. High-quality YSZ coatings with 5-6 m thickness were studied using SEM and XRD, the mechanical properties (Brenell and Moos hardness) of covered samples were compared with pure titanium characteristics. The regimes of titanium wafer pretreatment were optimized. It was shown that both 8Y2O3-92ZrO2 and 9Y2O3-10TiO2-92ZrO2 coatings increase the materialhardness.
