Description

Technical Field

[0001] The present invention belongs to the technical field of powder high-temperature alloy turbine disk preparation, and in particular relates to a device and method for cleaning the inner wall of a stainless steel container filled with powder high-temperature alloy. Background Art

[0002] As an important core hot end component of an aircraft engine, the turbine disk works under extremely harsh conditions and bears complex thermal and mechanical loads during flight. This requires that the turbine disk material has sufficient mechanical properties, especially the highest possible fatigue and endurance performance and good creep resistance, and powder high-temperature alloy parts can meet these requirements.

[0003] Turbine disk failures are mostly due to non-contained damage, and the vast majority of failure causes are internal inclusions, so inclusion control is crucial. To ensure the quality of powder high-temperature alloys, the types and quantities of inclusions must be strictly controlled during the manufacturing process. The disk manufacturing process includes powder making, powder screening and encapsulation, hot isostatic pressing, vacuum isothermal forging, heat treatment and other processes. Among them, quality control during the encapsulation process has a particularly significant impact on the quality and performance of the powder disk, especially inclusion control. Before powder encapsulation, the encapsulation must be welded, cleaned and other treatments. If the encapsulation is not cleaned properly, inclusions will directly enter the finished disk, causing the disk inclusions to exceed the standard and affecting the disk performance.
