NiCoCrAlTaReY,E FORU

**Product Overview: NiCoCrAlTaReY High-Performance Superalloy** NiCoCrAlTaReY is a premium-grade nickel-cobalt-chromium-aluminum-tantalum-rhenium-yttrium alloy engineered for extreme environment applications. As an advanced member of the MCrAlY (M = Ni, Co) coating family, it incorporates strategic additions of Tantalum (Ta) and Rhenium (Re) to deliver exceptional high-temperature strength, oxidation resistance, and microstructural stability. This alloy is primarily utilized as a bond coat in thermal barrier coating (TBC) systems or as a standalone protective layer in gas turbine engines and other high-temperature components. --- ### **Key Characteristics & Advantages** - **Enhanced High-Temperature Strength**: Rhenium and Tantalum provide solid-solution strengthening and stabilize the γ' phase. - **Superior Oxidation Resistance**: Forms a continuous, slow-growing Al₂O₃ scale for prolonged protection. - **Excellent Hot Corrosion Resistance**: Resists degradation in sulfur and salt-containing environments. - **Microstructural Stability**: Ta and Re retard coarsening of precipitates under thermal exposure. - **Thermal Fatigue Resistance**: Withstands cyclic thermal stresses in demanding applications. - **Optimized Coating Adhesion**: Yttrium enhances oxide scale adherence and spallation resistance. --- ### **Chemical Composition (Typical Weight %)** | Element | Content Range (%) | Function Description | |------------------|-------------------|-----------------------| | **Nickel (Ni)** | Balance | Forms γ matrix; provides ductility and base corrosion resistance. | | **Cobalt (Co)** | 15–25 | Enhances high-temperature strength and sulfidation resistance. | | **Chromium (Cr)**| 12–20 | Enables Cr₂O³ scale formation for oxidation/corrosion protection. | | **Aluminum (Al)**| 6–12 | Forms protective Al₂O₃ scale at high temperatures. | | **Tantalum (Ta)**| 2–6 | Strengthens γ' phase; improves oxidation resistance. | | **Rhenium (Re)** | 1–4 | Enhances creep strength and retards diffusion-driven degradation. | | **Yttrium (Y)** | 0.3–0.8 | Promotes oxide scale adhesion and coating durability. | | **Trace Elements**| ≤0.5 | Hf, Si, etc., for property optimization. | --- ### **Physical Properties** | Property | Typical Value | Test Conditions | |---------------------------------|------------------------|--------------------------| | **Density** | 7.9–8.3 g/cm³ | Theoretical density | | **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 | Room temperature | --- ### **Mechanical & Coating Properties** | Property | Typical Value | Test Method/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 & Specifications** NiCoCrAlTaReY complies with the following standards: - **AMS 4778**: Nickel/Cobalt Alloy Coatings (Plasma Spray). - **AMS 4779**: Nickel/Cobalt Alloy Coatings (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 of GE Aviation, Rolls-Royce, Pratt & Whitney, and Siemens Energy. --- ### **Applications** 1. **Aerospace Industry**: - Bond coat for TBCs on turbine blades, vanes, and combustor liners. - Protection for afterburners and exhaust components. 2. **Power Generation**: - Coatings for industrial gas turbine blades, transitions pieces, and combustors. - Hot gas path components in land-based turbines. 3. **Specialized Industrial Applications**: - High-temperature fixtures in heat treatment furnaces. - Components in nuclear and chemical processing environments. --- ### **Available Forms & Processing Methods** - **Gas-Atomized Powder**: Spherical powders with sizes (e.g., -45/+15 μm, -75/+45 μm). - **Sputtering Targets**: For Physical Vapor Deposition (PVD) processes. - **Wire Form**: For thermal spray applications. - **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 technical reference only.
