| 内容： | The invention provides an abradable ceramic seal material comprising yttria (Y 2 O 3 ) stabilized zirconia (ZrO 2 ) doped with alumina (Al 2 O 3 ). Furthermore, the invention provides a gas turbine system, comprising at least one turbine blade; an abrasive tip affixed on a top surface of the at least one turbine blade; a shroud housing the at least one turbine blade; and an abradable seal deposited between the at least one turbine blade and the shroud, wherein the abradable seal includes yttria stabilized zirconia that is doped with 0.5 to 1 wt. % of alumina. In addition, the invention provides a method of forming a powder for abradable coatings. |
