About Nickel-Graphite Powder [-325+400]
This powder is engineered for thermal spray processes where a controlled, friable coating is required. The nickel matrix provides corrosion resistance and bond strength, while the graphite component acts as a solid lubricant and dislocator, allowing the coating to be abraded away in a controlled manner during component rub. The specific -325+400 mesh cut (approximately 37 to 44 microns) is a standard particle size distribution that ensures consistent flowability and melting characteristics in the spray stream.
Thermal Spray Process Compatibility
The powder is suitable for application via standard thermal spray methods. The final process selection depends on the specific component geometry, base material, and desired coating properties. Our team can provide guidance on process fitment upon enquiry.
- HVOF (High Velocity Oxy-Fuel): Produces dense, well-bonded coatings with low oxide content.
- Plasma Spray: Offers flexibility for a wide range of substrates and coating thicknesses.
- Flame Spray: A cost-effective option for less demanding applications and dimensional restoration.
Industrial Applications
The primary function of a Nickel-Graphite coating is to serve as an abradable seal. In rotating equipment, it allows for zero-clearance fits between a rotating blade and a stationary casing, minimizing gas leakage and improving overall efficiency. Typical applications include compressor casings, turbine shroud seals, and labyrinth seal interfaces in aerospace, power generation, and industrial gas compression.
