  • Method for producing a sealing component with a body made of boron-containing superalloy and coated
    Patent number: 10875129
    Abstract: A method for producing a sealing component has a body made of superalloy covered by a coating to be placed in contact with a gas turbine blade tip. Steps are carried out in which: a) the new coating is produced by moulding from an alloy of a cobalt-nickel-chromium-aluminium-yttrium (CoNiCrAlY) type further containing between 0.5 and 5% by mass (wt %) of boron, and b) the superalloy body and the new coating are brazed together in order to obtain the said sealing component.
