Nickel-Graphite Powder 20-63 µm

About Nickel-Graphite Powder 20-63 µm

This nickel-graphite composite powder is engineered for thermal spray applications that demand controlled abradability. The nickel matrix provides bond strength and corrosion resistance, while the graphite phase ensures a low coefficient of friction and good rub compatibility. The 20–63 µm particle size range is optimized for consistent feeding and melting in common thermal spray systems.

Typical uses include compressor shroud coatings, turbine tip seals, and other clearance-control applications where the coating must wear preferentially during blade contact without damaging the rotating component. The powder is suitable for atmospheric plasma spray (APS), high-velocity oxy-fuel (HVOF), and flame spray processes, though specific parameter optimization is recommended for each system.

Key Features and Benefits

• Controlled particle size distribution: 20–63 µm range supports stable powder feeding and consistent melt characteristics across HVOF, plasma, and flame spray equipment.
• Abradable performance: The nickel-graphite composite delivers the rub-tolerance needed for clearance-control coatings in rotating machinery.
• Self-lubricating properties: Graphite content reduces friction during blade-tip contact, helping protect mating surfaces and maintain engine efficiency.
• Flexible pack sizes: Available in 5 kg tins, 10 kg tins, and 25 kg pails to suit both development trials and production runs.

Applications

Nickel-Graphite Powder 20-63 µm is primarily used in clearance-control and abradable coating systems. While the following applications represent common industry uses, actual suitability must be verified against your specific operating conditions, substrate material, and spray parameters.

• Compressor shroud coatings: Applied to stationary shroud surfaces in axial compressors to minimize blade-tip clearance losses while protecting blades from wear.
• Turbine tip seals: Used in gas turbine engines where the coating wears sacrificially during blade contact, maintaining tight clearances without damaging expensive rotating components.
• Industrial compressor components: Suitable for centrifugal and screw compressor casings where efficiency gains from reduced internal leakage are desired.
• General abradable applications: Any rotating machinery application requiring a sacrificial, rub-tolerant coating with good corrosion resistance and lubricity.

Selection and Handling Guidance

Before specifying this powder, consider your thermal spray process, substrate material, bond coat requirements, and target coating thickness. The 20–63 µm cut is a general-purpose distribution; tighter or shifted distributions may be available on request. Always confirm compatibility with your feed system, spray parameters, and post-coating machining or sintering steps.

Store powder in sealed containers in a cool, dry environment. Avoid exposure to moisture and extreme temperature fluctuations. Use appropriate personal protective equipment (PPE) when handling thermal spray powders, and follow your facility's safety protocols for metal and ceramic powder handling.
