Anti-vibration type dual-alloy turbine blisk and manufacturing method thereof

The invention belongs to turbine blisk technologies, and relates to an anti-vibration type dual-alloy turbine blisk and a manufacturing method thereof. The anti-vibration type dual-alloy turbine blisk is formed by welding a precision cast blade ring component and a sintered alloy blisk body in a diffusion mode through hot isostatic pressure, cut joints are formed between blade channels of the blisk, damping holes communicated with the cut joints are formed in the lower portion of the rim of the blisk, and friction dampers are arranged in the damping holes. The anti-vibration type dual-alloy turbine blisk is formed by welding the precision cast blade ring component and the sintered alloy blisk body in the diffusion mode through hot isostatic pressure, flexible selection and best usability matching of turbine disks and blades are achieved, meanwhile, the friction dampers are arranged on the blisk, the damping and vibration reducing effect is improved, the purposes of improving anti-fatigue ability of the blades and reducing vibration stress of the blades are achieved, and the anti-vibration type dual-alloy turbine blisk has great practical use value.
