Dieter R. Sporer has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
