Tungsten Carbide Nickel Powder [-200+400]

WC-Ni Powder for Wear Protection

The combination of hard tungsten carbide particles in a ductile nickel matrix gives this powder its characteristic balance of high hardness and good corrosion resistance. The -200+400 mesh size range is a widely specified cut for thermal spray, offering a controlled particle size that melts efficiently in the heat stream without overheating or unmelts, leading to homogeneous coating structures.

This powder is typically selected for applications where a tough, impact-resistant carbide coating is needed, such as on pump sleeves, plungers, rolls, and other machinery parts subject to sliding wear. The nickel binder provides a level of chemical resistance that makes the coating suitable for mildly corrosive environments, including exposure to seawater and certain acids, where a pure cobalt binder might be less appropriate.

Process Compatibility and Application Guidance

This powder grade is compatible with High Velocity Oxygen Fuel (HVOF), plasma, and flame spray systems. HVOF spraying is generally recommended to achieve the highest density and bond strength, minimizing decarburization and preserving the carbide phase. For best results, consult your equipment manual for optimal spray parameters, including spray distance, feed rate, and gas flows. Proper surface preparation, typically by grit blasting with a sharp angular abrasive, is essential to ensure a strong mechanical bond.
