MCrAlY Powder 45-90 µm

MCrAlY Powder for High-Temperature Surface Protection

MCrAlY (where M = Co, Ni, or Co/Ni) powders are the industry-standard choice for metallic bond coats and standalone overlay coatings in aggressive thermal environments. The 45-90 µm particle size distribution is optimized for consistent powder feeding and melting behavior in high-velocity oxy-fuel (HVOF) and atmospheric plasma spray (APS) systems. The resulting coatings exhibit excellent roughness for ceramic top-coat adhesion, strong substrate bonding, and long-term microstructural stability at elevated temperatures.

Selecting the correct MCrAlY composition (CoNiCrAlY, NiCoCrAlY, or NiCrAlY) depends on the specific corrosive environment, base material, and operating temperature. Our team helps you navigate these choices to match your coating specification.

Process Compatibility and Application Guidance

This powder grade is suitable for multiple thermal spray processes. HVOF spraying typically yields the densest, lowest-oxide coatings, making it ideal for applications demanding superior corrosion barrier properties. Plasma spraying offers flexibility for larger components and thicker deposits. Flame spray may be used for less critical repair work or where equipment portability is required.

For optimal results, confirm your specific process parameters with our technical team. We can assist with feed rate recommendations, surface preparation standards, and post-coating treatment advice based on your equipment and component geometry.
