Patent number: 8603930Abstract: The present invention provides a high-purity fused and crushed stabilized zirconia powder. The powder—with or without further processing, such as plasma spheroidization—is used in thermal spray applications of thermal barrier coatings (TBCs) and high-temperature abradables. The resulting coatings have a significantly improved high temperature sintering resistance, which will enhance the durability and thermal insulation effect of the coating.Type: GrantFiled: April 25, 2007Date of Patent: December 10, 2013Assignee: Sulzer Metco (US), Inc.Inventors: Jacobus C. Doesburg, Mitchell R. Dorfman, Liangde Xie

Patent number: 8187717Abstract: The invention is directed to a material and method for obtaining a ceramic abradable system for high temperature applications. High purity partially stabilized zirconia and/or hafnia base material has higher sintering resistance compared to conventional 6-9 weight percent yttria stabilized zirconia systems. The benefits of these systems are higher service lifetime and low thermal conductivity to achieve high operating temperatures. System includes a superalloy substrate, oxidation resistant bond coat and a thick ceramic abradable top coat. Total coating thickness is about 0.5-5 mm. In some applications an intermediate layer of high purity partially stabilized zirconia or a partially stabilized YSZ/MCrAlY cermet is applied over the oxidation resistant bond coat. In other applications an abradable system is applied on top of a grid. Additional benefits should be reduced blade wear at high operating conditions.Type: GrantFiled: December 3, 2010Date of Patent: May 29, 2012Assignee: Sulzer Metco (US) Inc.Inventors: Liangde Xie, Mitchell Dorfman, Richard Schmid, Jacobus C.

Patent number: 7955708Abstract: The invention is directed to high purity zirconia-based and/or hafnia-based materials and coatings for high temperature cycling applications. Thermal barrier coatings made from the invention high purity material was found to have significantly improved sintering resistance relative to coatings made from current materials of lower purity. The invention materials are high purity zirconia and/or hafnia partially or fully stabilized by one or any combinations of the following stabilizers: yttria, ytterbia, scandia, lanthanide oxide and actinide oxide. Limits for impurity oxide, oxides other than the intended ingredients, that lead to significantly improved sintering resistance were discovered. High purity coating structures suitable for high temperature cycling applications and for application onto a substrate were provided. In one structure, the coating comprises a ceramic matrix, porosity and micro cracks. In another structure, the coating comprises a ceramic matrix, porosity, macro cracks and micro cracks.Type: GrantFiled: September 13, 2006Date of Patent: June 7, 2011Assignee: Sulzer Metco (US), Inc.Inventors: Jacobus C.

Patent number: 7723249Abstract: The invention is directed to a ceramic material for use in thermal barriers for high temperature cycling applications and high temperature abradable coatings. The material is an alloy formed predominantly from ultra-pure zirconia (ZrO2) and/or hafnia (HfO2) that has uncharacteristically high sintering resistance to achieve a high service lifetime and low thermal conductivity to achieve high operating temperatures. In the material, oxide impurities such as soda (Na2O), silica (SiO2), alumina (Al2O3), titania (TiO2), hematite (Fe2O3), calcia (CaO), and magnesia (MgO) make up no more than 0.15 weight percent. The invention provides materials to produce a coating structure so that the changes in the coating microstructure over the in-service lifetime are either limited or beneficial.Type: GrantFiled: September 13, 2006Date of Patent: May 25, 2010Assignee: Sulzer Metco (US), Inc.Inventors: Jacobus C.
