Stellite-Type Cobalt Alloy Powder 10-30 µm

About Stellite-Type Cobalt Alloy Powder 10-30 µm

Stellite-type alloys are cobalt-chromium based compositions known for their exceptional resistance to wear, galling, and corrosion across a wide temperature range. The 10-30 µm particle size cut is specifically prepared for high-velocity oxy-fuel (HVOF) and plasma spray systems, where precise melting and high impact velocity produce coatings with low porosity and high bond strength.

This powder is suitable for protecting critical surfaces in demanding environments. Typical applications include valve seats, pump sleeves, bearing journals, and hot-section components where a combination of mechanical wear and chemical attack is present. The spherical or predominantly spherical morphology (typical for gas-atomized grades) promotes stable mass flow rates during spraying, reducing spitting and improving deposit efficiency.

Key Selection Considerations

• Particle size distribution: 10-30 µm is optimized for HVOF and plasma guns requiring fine, fully molten droplets.
• Chemistry: Cobalt-based matrix with chromium, tungsten, and carbon additions provides a balance of toughness and hard carbide reinforcement.
• Process compatibility: Confirm suitability for your specific gun model and parameters; our team can assist with grade matching.
• Pack integrity: Vacuum-sealed or inert-gas purged packaging maintains powder quality during storage and transit.

Typical Coating Properties

When applied correctly, Stellite-type coatings exhibit macrohardness values in the range of 38-48 HRC, depending on exact chemistry and spray parameters. The coatings retain hardness at elevated temperatures and offer excellent metal-to-metal wear resistance. Final properties are process-dependent; we recommend parameter optimization trials for critical applications.
