Post Process |  | 1. Removal of excess material: CNC machining or EDM and other processes are used to remove excess material to achieve complex structures and tight tolerances
2. Heat treatment: Release internal stress to strengthen the metal
3. Surface treatment: Increase the product's high temperature resistance and wear resistance through thermal barrier coating or wear-resistant coating | More Details |
Hot Isostatic Pressing (HIP) |  | 1. Densification of castings and 3D printed products: Eliminate internal porosity, shrinkage, segregation, and other defects.
2. Powder metallurgy: Consolidate powder into a fully dense sintered body and prevent excessive grain growth and segregation.
3. Diffusion bonding: Make the solid-solid, powder-solid, and powder-powder interface connection strength of dissimilar metals high, the microstructure is complete, the distortion is small, and the can realize the metallurgical bonding between different materials. | More Details |
Heat Treatment |  | 1. Increases superalloys' tensile, yield strength, toughness, and ductility by precipitating certain phases, like gamma-prime (γ') or carbide phases.
2. Optimizing Microstructure and Phase Transformation: Heat treatment refines the grain structure of the superalloy, resulting in improved fatigue resistance and mechanical strength.
3. Stress Relief and Enhancing Creep Resistance. | More Details |
Superalloy Welding |  | 1. A variety of single crystal blade LTP brazing repair brazing materials can be prepared in the form of paste, adhesive tape, and foil tape.
2. No brittle phase is generated at the weld, a complete isothermal solidification zone can be formed, and the high-temperature endurance life can reach more than 80% of the substrate.
3. The process hole brazing material coating and injection method for complex inner cavity structures can realize the mass production of blade process hole brazing. | More Details |
Thermal Barrier Coating (TBC) |  | 1. Thermal Insulation and Temperature Reduction: TBCs act as insulating layers that significantly reduce the heat transfer from the hot combustion gases to the underlying superalloy substrate.
2. Barrier Against Environmental Exposure: TBCs protect superalloy surfaces from harsh environments, including oxidation, corrosion, and exposure to corrosive agents like molten salts or abrasive particles.
3. Reduction of Thermal Stress: TBCs help to even out temperature distributions across the component, reducing thermal gradients that can lead to thermal fatigue and cracking. | More Details |
Superalloy CNC Machining |  | 1. Precision and Accuracy: (often within ±0.001mm)
