Tungsten Carbide Cobalt Powder [-270+400]

WC-Co Powder for Wear Protection

Tungsten carbide-cobalt (WC-Co) powders are a standard choice for creating dense, hard coatings with excellent sliding wear and abrasion resistance. The cobalt matrix provides toughness, while the hard tungsten carbide particles deliver the wear-fighting properties. This specific -270+400 mesh cut is fine enough to melt well in high-velocity thermal spray guns, yet coarse enough to maintain good flowability from powder feeders.

Typical applications include the coating of pump sleeves, compressor rods, hydraulic rams, paper mill rolls, and other industrial components that demand a hard surface to extend service life. The powder is suitable for HVOF (High Velocity Oxygen Fuel) systems, where high particle velocity produces coatings with low porosity and high bond strength. It can also be used in select plasma spray and powder flame spray setups, subject to process parameter optimization.

Selection and Handling Guidance

When selecting a thermal spray powder, particle size distribution is a primary factor. The -270+400 mesh designation indicates a controlled cut that helps achieve a stable spray plume and uniform coating microstructure. For best results, always confirm that your powder feeder, nozzle, and spray parameters are compatible with this mesh range. Store powder containers sealed in a cool, dry environment to prevent moisture pickup, which can cause feeding inconsistencies and coating defects.
