Title:
RUNNING-IN COATING FOR GAS TURBINES AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO2005056878
Kind Code:
A3
Abstract:
The invention relates to a running-in coating for gas turbines and a method for production of a running-in coating. The running-in coating serves to seal a radial gap between a housing (11) of the gas turbine and the rotating blades (10) themselves, whereby the running-in coating (13) is applied to the housing. According to the invention, the running-in coating is made from a CoNiCrAIY-hBN material. The CoNiCrAIY-hBN material is applied by means of thermal spraying, in particular thermal spraying.
