Nickel-Graphite Powder 45-90 µm

Understanding Nickel-Graphite Thermal Spray Powder

Nickel-graphite composite powders are engineered to produce coatings that can be sacrificially worn in tight-clearance environments, protecting more expensive components like turbine blades or compressor stators. The graphite phase provides natural dry lubrication, reducing friction during blade tip incursions, while the nickel alloy binder provides the necessary mechanical strength and corrosion resistance to survive the operating environment.

The 45-90 µm particle size distribution is a common cut for many thermal spray processes. This range typically offers a good balance between flowability through powder feeders and melting characteristics in the spray jet. Finer cuts may be available for specific processes; contact SPA2Z with your equipment details for a grade recommendation.

Typical Process Compatibility

This powder is generally considered for the following thermal spray processes, subject to final grade confirmation:

• Atmospheric Plasma Spray (APS): Commonly used for applying nickel-graphite abradable coatings in gas turbine clearance control.
• High-Velocity Oxy-Fuel (HVOF): Can produce denser, well-bonded coatings for applications requiring higher erosion resistance alongside abradability.
• Flame Spray: A cost-effective method for less demanding applications or for applying coatings to large, simple geometries.

Key Application Areas

Nickel-graphite coatings are primarily used as abradable clearance-control coatings. Common industrial applications include:

• Gas Turbine Engines: Applied to compressor and turbine shroud segments to allow blade tip incursion without damage, maintaining tight tip clearances for engine efficiency.
• Turbochargers: Used in compressor housings for similar clearance-control benefits in automotive and industrial turbochargers.
• Industrial Compressors and Pumps: Applied to stationary components to manage clearances and improve volumetric efficiency.
