Effects of Impurity Content on the Sintering Characteristics of Plasma-Sprayed Zirconia [PDF]

, 2007
Yttria-stabilized zirconia powders, containing different levels of SiO2 and Al2O3, have been plasma sprayed onto metallic substrates. The coatings were detached from their substrates and a dilatometer was used to monitor the dimensional changes they ...
