Tungsten Carbide Coatings

What is Tungsten Carbide?

Tungsten carbide is a chemical compound with the formula WC. It is an extremely hard material that is used in a variety of industrial applications, including mining and drilling. Tungsten carbide can be used in powdered, granular form for coatings, in large, crushed particles or agglomerations of very fine tungsten carbide dust, or it can be pressed and sintered into solid tungsten carbide shapes like saw blade teeth or wear pads. Tungsten carbide also has a high melting point and is resistant to corrosion.



Tungsten Carbide Coatings Applied with HVOF

Tungsten carbide coatings are known for their wear resistance and high hardness. When applied using the high-velocity oxygen fuel (HVOF) thermal spray process, these coatings can provide even greater levels of protection. The HVOF thermal spray process deposits tungsten carbide particles onto a substrate at high velocity and pressure, resulting in a coating that is highly densified and extremely smooth. This smooth surface helps to reduce friction and wear, making tungsten carbide coatings ideal for use in sliding wear applications. In addition, the HVOF process can be used to apply tungsten carbide coatings to complex geometries such as pump impellers and casings and turbine runners.

Benefits of Tungsten Carbide Coatings

Tungsten carbide coatings offer a number of benefits for cutting tools and other surfaces. First, tungsten carbide is one of the hardest industrial materials available, making it highly resistant to wear and tear, which can substantially extend the life of tools and surfaces that are subject to heavy use. Second, tungsten carbide coatings resist corrosion and other types of environmental damage. This can be especially helpful in environments where equipment and surfaces are exposed to chemicals or other corrosive substances. Finally, tungsten carbide coatings can improve the appearance of tools and surfaces. Carbide coatings can be ground to a mirror-like finish, adding aesthetic value to extreme durability. For these reasons, tungsten carbide coatings offer exceptional protection and performance.

Tungsten Carbide Coating Applications

Tungsten carbide coatings are often used on components that are subject to high-wear conditions, such as paper and converting machinery rollers, turbine blades, bearings, and pump impellers. In addition, tungsten carbide coatings can be used to repair damaged surfaces and extend the service life of tools and equipment. With their unique combination of hardness and durability, tungsten carbide coatings offer exceptional protection for machinery and components.
