Tungsten carbide is a commonly used coating material in thermal spraying technology, possessing relatively high hardness, strength, and chemical stability. It is often combined with supersonic spraying processes to prepare coatings, resulting in high density and bonding strength, effectively improving the wear and corrosion resistance of metal surfaces. There are many types of tungsten carbide coatings, and the hardness varies depending on the type and composition. The hardness of a tungsten carbide coating on a metal surface is not significantly related to its thickness, but rather directly related to the length of time it remains in the high-temperature zone. The hardness can generally reach HV1200 or higher.
Tungsten carbide spraying technology, as a new technology for strengthening and protecting metal surfaces, can not only repair damaged equipment but also strengthen and pre-protect new products, improving their durability. It can significantly save energy and materials, increase efficiency, and reduce costs. Therefore, thermal spraying technology plays an increasingly prominent role in national new and old kinetic energy conversion and additive manufacturing.
With the continuous development of thermal spraying technology, the protective performance of sprayed tungsten carbide coatings has also improved, and their application in industries such as power, steel, aerospace, and petrochemicals has become increasingly widespread.
