Relation Between the YSZ Powder Properties and Vacuum Plasma Spray Deposited Layers
Keywords:plasma spray, YSZ, SOFC.
Vacuum plasma spray deposition was used to produce yttrium stabilized zirconium (YSZ) (7 % mole) layers on ceramic and metal substrates using different conditions and way of preparation of powder. Powders were prepared in two ways, they were agglomerated and sintered or fused and crushed. It was found that YSZ layer chemical composition is the same as for used powders. Layers, produced by plasma spray deposition method with agglomerated and sintered powders, were more homogenous and dense.
