Title:
GAS TURBINE SHROUD WITH CERAMIC ABRADABLE COATING
Document Type and Number:
Japanese Patent JP2011169314
Kind Code:
A
Abstract:
To provide a gas turbine shroud with a ceramic abradable coating to be used for a gap adjusting component capable of improving turbine efficiency by reducing leakage of a fluid from a gap.
The ceramic abradable coating for a gas turbine includes: a bond layer; a thermal barrier ceramic layer; a porous ceramic abradable layer (hardness is RC15Y:80±3). The porous ceramic abradable layer is provided with a slit groove by machining, and a width of a rectangular cross section of the ceramic abradable layer divided by the slit is set within a range of 2-7 mm.
