product key technologies
Ultra high purity melting Surface strengthening and post-treatment
Using electron beam melting (EBM) or vacuum arc melting (VAR), the alloy composition is precisely controlled: hafnium (Hf) 9-11%, titanium (Ti) 0.7-1.3%, zirconium (Zr) ≤ 0.7%, niobium matrix purity ≥ 99.9%, key impurities oxygen (O) ≤ 100ppm, carbon (C) ≤ 0.015%.
Electromagnetic stirring ensures uniform distribution of elements and avoids segregation.
Gradient coating: Spray HfC SiC composite coating (thickness 10-20 μ m) to achieve an oxidation weight loss rate of ≤ 0.5mg/cm ² · h 15 at 1400 ℃;
Vacuum annealing: Stress relief at 1100-1250 ℃, and stable tensile strength at room temperature of 380-450MPa.
Large scale billet processing
Squeezing and opening:
Under the protection of inert gas at 1200 ℃, squeeze the φ 150-300mm ingot into a square billet (suitable for 80mm thick plate).
Package rolling:
6-20mm medium plate: stainless steel sheath protection, multi pass warm rolling (single pass deformation ≤ 15%);
20-80mm thick plate: High temperature forging+rolling composite process to solve the problem of uneven deformation in the core.
Core application areas
Aerospace propulsion system
- Rocket engine nozzle: 30-80mm thick plate is used for the nozzle extension section (such as SpaceX Raptor engine), which can withstand 1700 ℃ gas erosion;
- Attitude thruster housing: fuel chamber made of 6-15mm sheet metal, with high temperature strength to ensure propulsion efficiency.
Nuclear energy equipment
- Reactor neutron shield: 50-80mm thick plate serves as a radiation protection layer, maintaining a low neutron absorption cross-section (0.11 bar) under irradiation at 1300 ℃;
- Nuclear fuel support: 20-30mm plate support components, resistant to liquid metal corrosion.
Ultra high temperature industrial components
- Hot pressing mold: 40-60mm sheet material for manufacturing guide columns/templates, resistant to 1500 ℃ thermal fatigue (life increased by 3 times);
- High temperature furnace heating strip: 6-10mm thin plate bending forming, anti-oxidation coating extends service life.
C103 board achieves full thickness coverage of 6-80mm through EBM/VAR melting, cladding rolling, and gradient coating technology. Its high temperature strength (1200 ℃ ≥ 85MPa) and lightweight characteristics (density 8.57g/cm ³) make it the preferred material for aerospace nozzles and nuclear energy shields. Future needs to break through 1400 ℃ long-lasting antioxidant coating and compatibility with additive manufacturing.
