Directional Solidification Crystal Casting Blade
Manufacturing Method Of Single Crystal Turbine Blade
The following are common manufacturing processes for single crystal turbine blades:
Single crystal growth: CZ method (CZ method), zone melting method (FZ method) and Bridgman method can be used to grow single crystals
Blade processing:
Casting: For smaller blades, it can be cast directly from a single crystal material. But this presents a challenge to size control and shape accuracy.
Cutting: The single crystal material is very hard and brittle, so it needs to be cut with diamond tools. This requires highly accurate machine tools and specialized processing technology.
Edm: A contactless machining method that uses electrical discharge to remove material and can be used to make blades of complex shapes.
Laser processing: Laser processing can be used for cutting, engraving and welding, and can be used for fine machining of single crystal blades.
Blade surface treatment:
Heat treatment: In order to improve the heat resistance and strength of the blade, heat treatment is required.
Surface coatings: Commonly used coating materials include ceramic coatings, metal coatings and composite coatings to improve durability.
Blade detection and inspection:
Non-destructive testing: Use X-ray, ultrasonic and other methods to detect whether there are defects inside the blade.
Performance test: The strength, heat resistance and fatigue properties of the blades are tested to ensure that they meet the requirements.
