NiCoCrAlTaReY ,E FORU

**Product Introduction: NiCoCrAlTaReY Alloy** NiCoCrAlTaReY is an advanced nickel-cobalt-chromium-aluminum-tantalum-rhenium-yttrium superalloy designed for extreme high-temperature applications. As part of the MCrAlY family, this alloy incorporates strategic additions of Tantalum (Ta) and Rhenium (Re) to significantly enhance mechanical strength, oxidation resistance, and microstructural stability under prolonged exposure to aggressive thermal and corrosive environments. It is widely used as a bond coat in thermal barrier coating (TBC) systems or as a standalone protective coating in aerospace, power generation, and industrial turbine components. --- ### **Key Features & Advantages** - **Exceptional High-Temperature Strength**: Enhanced by solid-solution strengthening from Re and Ta. - **Superior Oxidation & Hot Corrosion Resistance**: Forms a stable, continuous Al₂O₃ scale. - **Improved Microstructural Stability**: Tantalum and Rhenium retard coarsening of γ' precipitates. - **Excellent Thermal Fatigue Resistance**: Withstands repeated thermal cycling. - **Enhanced Coating Adhesion**: Yttrium promotes oxide scale adhesion and spallation resistance. --- ### **Chemical Composition (Typical Weight %)** | Element | Content Range (%) | Role/Function | |------------------|-------------------|---------------| | **Nickel (Ni)** | Balance | Forms the γ matrix; provides base toughness. | | **Cobalt (Co)** | 15–25 | Enhances high-temperature strength and corrosion resistance. | | **Chromium (Cr)**| 12–20 | Provides oxidation and hot corrosion resistance via Cr₂O₃ scale. | | **Aluminum (Al)**| 6–12 | Forms a protective Al₂O₃ layer. | | **Tantalum (Ta)**| 2–6 | Strengthens γ' phase; improves oxidation resistance. | | **Rhenium (Re)** | 1–4 | Enhances creep strength and retards diffusion. | | **Yttrium (Y)** | 0.3–0.8 | Improves scale adhesion and coating durability. | | **Other Elements**| ≤0.5 | Trace elements (e.g., Hf, Si) for tailored properties. | --- ### **Physical Properties** | Property | Typical Value | Conditions/Remarks | |---------------------------------|------------------------|-----------------------------| | **Density** | 7.9–8.3 g/cm³ | | | **Melting Range** | 1320–1400°C | | | **Thermal Expansion Coefficient**| 13.0–15.5 × 10⁻⁶/°C | 20–1100°C range | | **Thermal Conductivity** | 11–15 W/m·K | At 900°C | | **Young’s Modulus** | 190–230 GPa | At room temperature | --- ### **Mechanical & Coating Properties** | Property | Typical Value | Test Conditions | |------------------------|----------------------|----------------------------| | **Coating Hardness** | 350–500 HV₃₀₀ | As-coated (HVOF/Plasma) | | **Bond Strength** | >75 MPa | ASTM C633 | | **Porosity** | <1.5% | Optimized spray parameters | | **Oxidation Rate** | <0.3 mg²/cm⁴h | 1150°C, 100 hours | | **Creep Resistance** | Excellent | Due to Re/Ta additions | --- ### **International Standards** NiCoCrAlTaReY complies with the following standards and specifications: - **AMS 4778**: Nickel/Cobalt Alloy Coatings for Plasma Spray. - **AMS 4779**: Nickel/Cobalt Alloy Coatings for HVOF Spray. - **ASTM B214**: Sieve Analysis of Metal Powders. - **ASTM B213**: Flow Rate of Metal Powders. - **ISO 14919**: Thermal Spraying – Wires, Rods, and Cords. - **OEM Specifications**: Meets proprietary requirements from GE, Rolls-Royce, Pratt & Whitney, and Siemens. --- ### **Product Applications** 1. **Aerospace**: - Bond coat for TBCs on high-pressure turbine blades and vanes. - Combustor liners, afterburners, and nozzle components. 2. **Power Generation**: - Coatings for industrial gas turbine blades and vanes. - Hot gas path components in land-based turbines. 3. **High-Temperature Industrial**: - Heat treatment fixtures, nuclear components, and chemical processing equipment. --- ### **Available Forms & Processing Methods** - **Gas-Atomized Powder**: Spherical powders with controlled size distribution (e.g., -45/+15 μm, -75/+45 μm). - **Sputtering Targets**: For EB-PVD and PVD coating processes. - **Coating Processes**: - High Velocity Oxygen Fuel (HVOF) - Low Pressure Plasma Spray (LPPS) - Electron Beam Physical Vapor Deposition (EB-PVD) - Cold Spray --- **Disclaimer**: *The information provided is for reference purposes only.
