What is the structure and application of tungsten carbide spray coating?

Tungsten carbide spraying is the process of combining tungsten carbide alloy in the form of a coating with a substrate to produce a tungsten carbide wear-resistant layer. Industrial parts adopt supersonic flame spraying tungsten carbide sealing, which improves the wear resistance and corrosion resistance of the product. Improve product performance and service life.

In oil and gas screw drilling tools, spraying Wc10Co4Cr tungsten carbide improves the wear resistance and corrosion resistance of the screw drilling tool due to the erosion of sediment and saturated salt water, and extends the service life of the screw.

Spray tungsten carbide is a common metal coating in the metal manufacturing industry, which has a series of characteristics such as corrosion resistance and wear resistance. Tungsten carbide is a fine powder, usually gray in color. Tungsten carbide powder can be sintered and pressed into decorative, cutting tools or engineering machinery parts. But if tungsten carbide is combined with a small amount of metal powder (usually cobalt, chromium, or nickel), spraying tungsten carbide on the surface of the metal object can form a tungsten carbide coating.

Although tungsten carbide is a hard and brittle ceramic material, cobalt, chromium, and nickel are doped when used as tungsten carbide coatings. Metal ceramic composite coatings combine the ductility of metal materials with the high hardness of ceramic tungsten carbide, resulting in excellent performance.

Tungsten carbide has many potential applications, including thermal spray tungsten carbide coatings. These tungsten carbide coatings are common on brake discs of high-performance cars. Carbon tungsten coating improves performance and maintenance intervals, reducing brake dust. Manufacturing and processing tools is one of the important applications of tungsten carbide. These tools utilize the material's wear resistance and heat resistance. They are usually used for high-precision or large-scale production, and the steel wears out too quickly.

Tungsten cobalt carbide composite materials are commonly used in the design of ammunition such as armor piercing shells. The strength of tungsten carbide is also common in mining and foundation drilling. In sports, it is often used as a material for hiking or skiing poles. Tungsten carbide spraying is generally used for wearing decorative and surgical equipment. It provides better performance than stainless steel, but is more expensive and requires finer processing.
