Abstract

The present invention provides a coating device for a single-wheel integral blisk of an axial-flow compressor, which includes a vacuum chamber and a fixture. The blisk is installed in the vacuum chamber through the fixture. Layer deposition targets, the four coating deposition targets are respectively the first target, the second target, the fourth target and the fifth target, wherein the second target and the fourth target are placed on the air inlet side of the blisk; The first target is placed on the side of the exhaust side of the blisk; the fifth target is placed on the side of the blade tip; the application of the present invention can greatly improve the reliability and service life of the axial-flow single-wheel integral blisk in complex environments , has significant economic benefits.

Description

technical field [0001] The invention belongs to the field of mechanical engineering, and relates to a coating device for a single-wheel integral blisk of an axial-flow compressor. Background technique [0002] Turbomachinery compressors all use blades with an airfoil through which air is directed and work is performed during operation. The integral blisk compressor is an important part of aeroengine and other impeller machinery. The integral blisk adopts the design idea of ​​integrating the blade and the turntable, which can reduce the weight, eliminate the adverse effects of friction and vibration on the connecting parts, and improve the performance of the system under high-speed rotation. stability. In the process of compressing and guiding the airflow, it is easily affected by the environment, and sand, water droplets and other particles are inhaled with the airflow, making the surface of the overall blisk blade vulnerable to impact and erosion by the particles and liqui...
