NiCrAlY Target
Overview
Nickel-Chromium-Aluminum-Yttrium (NiCrAlY) targets are advanced alloy materials designed for deposition processes like sputtering and electron beam evaporation. They are part of the MCrAlY family (where M denotes Ni, Co, or Fe), valued for forming protective coatings in extreme environments. The alloy typically contains 60-80% nickel, 15-25% chromium, 5-12% aluminum, and 0.5-1.5% yttrium. Yttrium enhances oxide layer adhesion, critical for long-term performance. These targets are manufactured via vacuum melting and precision machining to ensure compositional homogeneity and dimensional accuracy.
Physical and Chemical Properties
NiCrAlY targets exhibit a dense, metallic microstructure with high thermal conductivity (~12 W/m·K) and low electrical resistivity. The aluminum content forms a protective Al₂O₃ layer at high temperatures, while chromium improves corrosion resistance via Cr₂O₃ formation. Key mechanical properties include a Vickers hardness of 200-300 HV and tensile strength of ~600 MPa. The alloy maintains ductility even at elevated temperatures (up to 1100°C), enabling crack-resistant coatings. Its coefficient of thermal expansion (14-16 μm/m·°C) matches common substrate materials like superalloys.
Main Applications
Primary use is in thermal barrier coating (TBC) systems for gas turbine components (blades, vanes, combustors) in aerospace and power plants. The target material is deposited as a bond coat to protect underlying metals from oxidation and thermal stress. Secondary applications include marine engine parts, industrial furnace components, and chemical processing equipment. Recent R&D explores its use in solid oxide fuel cells (SOFCs) and nuclear reactors due to its radiation tolerance. Coatings from NiCrAlY targets typically last 20,000-50,000 operational hours in turbines.
Safety and Storage
While solid targets pose minimal risk, machining generates fine metal dust requiring HEPA filtration and NIOSH-approved respirators. Yttrium compounds demand special handling due to potential lung toxicity (OSHA PEL: 1 mg/m³ for yttrium). Store targets in sealed containers with desiccants to prevent surface oxidation. Argon or nitrogen purging is recommended for long-term storage. Avoid contact with acids or halogenated solvents, which may cause pitting. Waste disposal should follow local metal recycling regulations.
B2B Procurement Guide
Specify critical parameters: composition tolerances (e.g., ±1% for Al/Y), density (>95% theoretical), and impurity limits (e.g., O₂ <500 ppm). Standard diameters range from 2" to 8" with thicknesses of 0.25"-0.5". Leading suppliers include Praxair Surface Technologies, H.C. Starck, and Beijing Guanli. MOQs vary from 1-10 pieces, with lead times of 4-8 weeks for custom compositions. Request certification including ICP-MS analysis reports and ultrasonic inspection data for defect-free targets. Consider FOB terms for international shipments to avoid oxidation during transit.
