Abstract

Official abstract text for this publication.

The invention relates to a high-pressure compressor of a gas turbine having at least one blisk, specifically a disk with a plurality of blades that are disposed on the disk, wherein the blisk has at least one titanium material from the group that comprises Ti-6246 and Ti-6242, wherein the materials of the disk and the blades of the blisk differ in their chemical composition and/or their microstructure. The blades are welded to the disk, in particular, by means of a pressure welding method supported by high-frequency current, whereby the current is conducted through the joint surfaces and leads to local limited melting therein.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for the production of an integrally bladed rotor of a high-pressure compressor having a compression ratio of more than 30 to 1, the method comprising the steps of: providing a disk that is formed from Ti-6246 or lamellar Ti-6246; providing blades that are formed from Ti-6242 or bimodal Ti-6246, the blades having joint surfaces that can each be secured to respective joint surfaces on the disk; heating and melting the joint surface on one of the b…
