Abstract

See full text

There is proposed a method of producing an integrally bladed rotor, preferably a so-called “blisk” for a turbomachine, the method including the steps of: providing a rotor disc having a plurality of spaced-apart radial protrusions formed integrally around its perimeter; and forming a respective aerofoil-shaped blade extending radially generally outwardly from each of the protrusions via laser deposition. Each protrusion preferably extends radially outwardly from a circumferential body part of the rotor disc by a distance which is greater than the radially inward penetration of a heat-affected zone arising from the laser deposition used to form the respective blade.
