FIELD: mechanical engineering; turbines.
SUBSTANCE: proposed abradable seal is designed for turbines. It contains new cellular made of metal foil or sheet of high manufacturability facilitating process of soldering and featuring high resistance to oxidation and high structural integrity after soldering to metal support structure. Foil or sheets of alloy MCrAIY (where M-Ni, Fe, Co or their combinations) are good manufacturing of such cellular structure. Such making of abradable seal provides high and long-time dimensional stability at high temperature.
EFFECT: improved quality of seal.
