The Preparation of Anti-corrosion And Wear-resistant Tungsten Carbide Coating by Supersonic Spraying with Tension Rollers

Application and Advantages of Metal Functional Coatings:

Wear-resistant coating: By adding a hard metal alloy coating, such as tungsten carbide or chromium alloy, to the surface of the tension roller, the wear resistance of the tension roller can be significantly improved and its service life can be prolonged.

2. Corrosion-resistant coating: In corrosive environments, using metal or alloy coatings with excellent corrosion resistance, such as nickel-based alloys and zinc-based alloys, can protect tension rollers from chemical erosion.

3. Low-friction coating: By using metal coatings with low friction performance, such as chromium plating and PVD titanium nitride coating, the friction between the tension roller and the material can be reduced, wear can be decreased, and production efficiency can be improved.

4. Anti-adhesion coating: For the production process of materials that are prone to adhesion, using metal coatings with anti-adhesion properties, such as polytetrafluoroethylene (PTFE) and siloxane, can prevent the material from adhering to the surface of the tension roller, ensuring the smooth progress of the production process.

5. Thermal stability coating: In high-temperature environments, by adding metal or alloy coatings with high thermal stability, such as nickel-chromium alloy, molybdenum alloy, etc., the thermal stability of tension rollers can be enhanced and thermal deformation can be prevented.

The application of thermal spraying technology on the surface of tension rollers has achieved remarkable results. For instance, in industries such as papermaking, textile, and plastic film, the preparation of metal functional coatings can effectively enhance production efficiency and reduce maintenance costs. With the continuous development of materials science and coating technology, more high-performance and multi-functional metal functional coatings will emerge in the future to meet the constantly changing demands in industrial production.
