Title:
摩耗性を有するジスプロシア安定化ジルコニア
Document Type and Number:
Japanese Patent JP5128185
Kind Code:
B2
Abstract:
Ceramic abradable materials, in particular thermally sprayablc ceramic abradable powder materials, and abradable seals formed by thermally spraying the materials include dysprosia (Dy 2 O 3 ) and zirconia (ZrO 2 ). Coatings are porous whereby the porosity, in part, is induced by plastic or fugitive phases. Abradable seal coatings comprising dysprosia and zirconia exhibit improved thermal shock and sintering resistance and can be worn into tolerance by untreated, bare turbine blades, at least in certain regimes of relative blade speed and coating porosity. Ceramic abradable seal coatings comprising dysprosia and zirconia can be used up to 1200 °C.
