Traction coatings are used on rolls and various rotating components to control the friction, binding, or adhesion between two surfaces. These coatings are beneficial in increasing traction and preventing slipping on rotational components such as on pulp and paper rolls and reel drums. Because the traction of the coating depends substantially on the degree of its surface roughness, nearly any material can be used to create a traction coating. However, in most applications where a traction coating is required there is also a great amount of wear present and, therefore, the most common traction coating materials are carbides, stainless steels, and nickel alloys.
Western Machine Works are experienced in the application of traction coatings to various types of rolls and rotating components. Traction coatings are used to increase coating integrity and customize surface textures, increase roll runnability, reduce downtime, and extend the service life of the equipment.
Advantages of Traction Coatings
Western Machine Works uses thermal spray procedures to add traction textures to your industrial components, according to your required specifications. Because these are bonded to the substrate, they are durable and long lasting. Substances such as tungsten carbides, stainless steel, or nickel alloys are commonly chosen for their resistance to wear under continuous use in production facilities.
Traction Coatings Help With the Following:
- Reduced slippage
- Better tension control
- Reduce surface wrinkles
- Ensure tight starts
- Better web tracking
Thermal Spray Process for Traction Coatings
Different processes can be used to achieve the desired traction for a component or part. Typically, these would be twin-wire arc thermal spray, or flame spray. In electric twin-wire arc spraying, an electric charge runs between two wires to raise the temperature, which is then accelerated through an extension nozzle, and the coating is applied to the surface. In flame spray coatings, there extension nozzle is absent, but the coating is applied to a wider area of the component surface.
Release agents are added to the coating to reduce the amount of material embedded in the texture of the component as the machinery runs.
