Abstract: A method for surface blasting of integrally bladed rotors is disclosed. In an embodiment, the method includes: a) providing an integrally bladed rotor; b) providing a vibratory grinding. system; c) arranging the integrally bladed rotor in a grinding container of the vibratory grinding system; d) filling the grinding container of the vibratory grinding system with blasting balls; and e) operating the vibratory grinding system filled with the blasting balls and the integrally bladed rotor to accelerate the blasting balls, wherein the accelerated blasting balls simultaneously strengthen the integrally bladed rotor on the surfaces of all the rotor blades and in the annular space between neighboring rotor blades.
