Self-Fluxing Nickel Alloy Powder 10-30 µm

About Self-Fluxing Nickel Alloy Powder (10-30 µm)

Self-fluxing nickel alloy powders contain boron and silicon, which act as fluxing agents during spraying. These elements lower the melting point and promote oxide removal, helping the sprayed particles wet the substrate and form a dense, low-porosity coating. The result is a metallurgically bonded layer with good hardness and resistance to wear and corrosion in many industrial environments.

The 10–30 µm particle size range is a fine cut commonly specified for high-velocity oxy-fuel (HVOF) spraying, where controlled particle melting and high impact velocity produce coatings with low oxide content and high bond strength. This size range can also be used in select plasma and flame spray setups, depending on torch configuration and feed parameters.

Typical coating characteristics

• Self-fluxing chemistry reduces the need for separate flux additions during spraying.
• Fine particle size supports smooth as-sprayed surface finish and good machinability after fusing or grinding.
• Coatings exhibit resistance to abrasive wear, cavitation, and oxidation at elevated temperatures.
• Fusing after spraying can further densify the coating and improve metallurgical bonding.

Common industrial uses

This powder grade finds use across industries that rely on thermal spray for component life extension. Typical applications include:

• Repair and dimensional restoration of shafts, journals, and bearing seats.
• Wear-resistant coatings on pump sleeves, plungers, and valve components.
• Corrosion-resistant overlays on process equipment in chemical, petrochemical, and power generation plants.
• Glass mould plungers and other hot-end tooling requiring oxidation resistance.

Because coating performance depends heavily on substrate preparation, spray parameters, and post-spray treatment, SPA2Z recommends discussing your specific component, base material, and operating conditions before finalising a powder grade.
