Self-Fluxing Nickel Alloy Powder [-170+325]

About Self-Fluxing Nickel Alloy Powder [-170+325]

Self-fluxing nickel alloy powders are widely used in thermal spray and spray-and-fuse operations to deposit dense, well-bonded coatings. The -170+325 mesh particle size distribution is a common specification for HVOF (High Velocity Oxygen Fuel) and plasma spray systems, offering a balance between flowability and melt characteristics. The self-fluxing nature, typically derived from boron and silicon additions, eliminates the need for a separate flux, simplifies the coating process, and helps achieve low-porosity deposits.

Thermal Spray Process Compatibility

This powder grade is suitable for evaluation across multiple thermal spray processes. The final selection depends on your specific coating requirements, substrate material, and desired hardness.

• HVOF Spraying: Produces dense, well-adhered coatings with low oxide content, ideal for wear and corrosion protection.
• Plasma Spraying: Offers high deposition rates and is suitable for a wide range of component geometries.
• Flame Spraying / Spray-and-Fuse: A cost-effective method for applying and fusing coatings, often used for rebuilding worn shafts and parts.

Industrial Applications

Procurement professionals and engineers source this type of powder for surface engineering tasks that demand reliable performance under abrasive wear, fretting, or corrosive conditions. Typical application areas include:

• Rebuilding and hardfacing of worn industrial shafts, pump sleeves, and plungers.
• Protective coatings on boiler tubes, valves, and seats exposed to high-temperature erosion.
• Glass mould plungers and other components requiring a combination of wear resistance and release properties.
• General maintenance, repair, and overhaul (MRO) operations in heavy engineering and process industries.

Selection and Handling Guidance

To achieve consistent coating results, proper powder handling and storage are essential. Keep the powder in its original, sealed container in a cool, dry environment to prevent moisture absorption, which can affect flow and cause spray inconsistencies. Always confirm the specific alloy chemistry and hardness range with our team to match your base material and service conditions. A sieve analysis certificate can be provided on request to verify the particle size distribution.
