  • Dysprosia stabilized zirconia abradable
    Patent number: 7981530
    Abstract: Ceramic abradable materials, in particular thermally sprayable ceramic abradable powder materials, and abradable seals formed by thermally spraying the materials include dysprosia (Dy2O3) and zirconia (ZrO2). 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.
    Type: Grant
    Filed: June 7, 2007
    Date of Patent: July 19, 2011
    Assignee: Sulzer Metco (US), Inc.

  • Air-cooled turbine blade
    Patent number: 6439847
    Abstract: An air-cooled turbine blade (1) is provided in the cavity (5) of the blade body (3) with an insert (6) made of a shape memory alloy. Due to the contraction of the insert (6) after a certain temperature threshold value is exceeded, the cooling system (12) of the turbine blade (1) is enlarged in the interior. The size of the cooling system (12) (effectiveness of the cooling, cooling-air quantity, size of cooling passages) is therefore advantageously dependent upon the ambient temperature.
