MCrAlY Powder [-140+325]

MCrAlY Powder for Thermal Spray Bond Coats

MCrAlY coatings serve as the critical interface between the substrate and the ceramic topcoat in thermal barrier coating (TBC) systems. The aluminum content forms a dense, adherent alumina scale at high temperatures, while yttrium improves scale adhesion and spallation resistance. Chromium provides hot-corrosion protection, and the cobalt or nickel base delivers structural stability. The -140+325 mesh particle size range is engineered for consistent powder feeding, stable melting in the thermal spray jet, and a homogeneous as-sprayed coating microstructure.

Process Compatibility and Selection

This powder cut is suitable for High-Velocity Oxygen Fuel (HVOF), atmospheric plasma spray (APS), and vacuum plasma spray (VPS) processes. HVOF spraying typically yields dense, low-oxide coatings with high bond strength, while plasma spray offers flexibility for larger components and field applications. The optimal process depends on your component geometry, coating thickness requirement, and desired oxide content. SPA2Z can help you select the right MCrAlY grade and process combination based on your operating conditions.

Pack Options and Handling

Standard pack options include 5 kg tins, 10 kg tins, and 25 kg pails. Each container is sealed to protect the powder from moisture and contamination during storage and transit. We recommend storing MCrAlY powder in a cool, dry environment and minimizing exposure to humidity before spraying. For high-volume requirements, contact us to discuss bulk packaging and scheduled deliveries.
