MCrAlY Powder 10-30 µm

MCrAlY Powder for Thermal Spray Bond Coats

MCrAlY (M–Chromium–Aluminum–Yttrium) powders form the backbone of many high-temperature coating systems. Applied as a bond coat beneath ceramic topcoats, the MCrAlY layer provides a rough, oxidation-resistant surface that promotes adhesion and protects the base alloy from aggressive environments. The 10–30 µm cut is particularly suited to fine-feature components and thin, uniform bond coats where precise thickness control matters.

This powder is compatible with HVOF (High Velocity Oxygen Fuel), atmospheric plasma spray (APS), and vacuum plasma spray (VPS) systems. The fine particle range enables high deposition efficiency and smooth as-sprayed surfaces, reducing the need for extensive post-coating finishing.

Typical Applications

• Gas turbine blades and vanes: Bond coats under thermal barrier coatings (TBCs) for hot-section components.
• Aerospace engine parts: Oxidation and hot corrosion protection on combustor liners, afterburner flaps, and seals.
• Industrial gas turbines: Protective overlays on buckets, nozzles, and transition pieces.
• Diesel engine components: Piston crowns and valve faces exposed to high-temperature corrosion.
• Repair and overhaul: Restoration of worn MCrAlY coatings during component refurbishment.

Powder Selection and Process Compatibility

Selecting the right MCrAlY grade depends on the base alloy, operating temperature, and spray process. The 10–30 µm range is optimized for HVOF and plasma spray where fine particle melting and high velocity produce dense, well-bonded coatings. For flame spray applications, parameter adjustments may be required to achieve full particle melting. SPA2Z helps buyers confirm process fit before quotation—share your spray system details and coating specification during enquiry.

Pack Sizes and Availability

Standard pack options include 5 kg tins, 10 kg tins, and 25 kg pails. Custom packaging may be available for bulk orders. Because MCrAlY powder chemistry varies by application (NiCoCrAlY, CoNiCrAlY, NiCrAlY, etc.), every order is matched to the buyer's grade requirement. Lead time and pricing are confirmed on enquiry.
