Overview of Tungsten carbide cobalt chrome alloy WC10CO4CR HVOF Powder

Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.

When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.

Feature of Tungsten carbide cobalt chrome alloy WC10CO4CR HVOF Powder

The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

Parameters of Tungsten carbide cobalt chrome alloy WC10CO4CR HVOF Powder

Tungsten carbide cobalt-chrome alloy (WC-Co-Cr) with the chemical composition WC10Co4Cr HVOF (High Velocity Oxygen Fuel) powder typically has the following parameters:

1. Chemical Composition:
– Tungsten Carbide (WC): 10% by weight
– Cobalt (Co): 4% by weight
– Chrome (Cr): The remaining balance, usually around 86% (since WC is 10% and Co is 4%, that leaves approximately 86% for Cr)
– Additional elements: May also contain small amounts of niobium (Nb), titanium (Ti), or molybdenum (Mo) for improved wear resistance and strength.

2. Particle Size Distribution (PSD):
– Widely available in various sizes, typically ranging from submicron to several micrometers for better control over coating properties. Common particle size specifications include 325 mesh (45 microns), 600 mesh (74 microns), or 1000 mesh (150 microns).

3. Shape:
– Mostly in spherical or irregular shapes, which promote uniform distribution during the manufacturing process.

4. Density:
– Generally, WC-Co-Cr powders have a high density, around 14 to 16 g/cm³, contributing to the dense coatings produced by HVOF.

5. Hardness:
– Due to the high tungsten content, WC10Co4Cr has excellent hardness, typically HV1000 or higher, making it suitable for wear-resistant applications.

6. Thermal Conductivity:
– High thermal conductivity, which helps maintain efficient heating during the HVOF process and minimizes thermal stress on the substrate.

7. Melting Point:
– The melting point of WC-Co-Cr alloy is quite high, around 3692°C (6660°F), ensuring the formation of a strong bond with the substrate during deposition.

8. Processing Parameters for HVOF:
– Deposition Temperature: Typically in the range of 3000-4000°C (5432-7232°F).
– Pressure: Atmospheric pressure or slightly above.
– Oxygen Pressure: High, around 20-40 bar, for the generation of high-speed oxygen fuel jet.
– Particle Velocity: Very high, up to several thousand meters per second, which results in a fine and dense coating.

9. Application:
– Primarily used for wear-resistant coatings on cutting tools, dies, and other industrial components exposed to abrasive or erosive environments.

Please note that specific parameters may vary depending on the manufacturer and the desired properties of the final coating. It’s essential to consult the supplier for detailed information on the exact powder parameters.
