The nature, structure and application of sprayed tungsten carbide

       In the metal manufacturing industry, spraying tungsten carbide is a relatively common metal coating. It has a series of characteristics that make it stand out, such as corrosion resistance and abrasion resistance. Today, Taizhou Hai Ruisi will introduce spraying to everyone. Some properties of tungsten carbide and its structure and applications.



What is sprayed tungsten carbide

Tungsten carbide is a fine powder, and its color is usually gray. Tungsten carbide powder can be formed by sintering and pressed into jewelry, cutting tools or engineering machinery parts.

But if tungsten carbide is used in combination with a small amount of metal powder (usually cobalt, chromium or nickel), it is sprayed with tungsten carbide, which can form a tungsten carbide coating on the surface of the metal object.

Is sprayed tungsten carbide a metal?

Although tungsten carbide is a hard and fragile ceramic material, when used as a tungsten carbide coating, it will be mixed with cobalt, chromium and nickel. This cermet composite coating combines the ductility of metal materials And the high hardness of ceramic tungsten carbide, so as to obtain excellent performance.



Application of spraying tungsten carbide

There are many potential applications for tungsten carbide, including thermal spray tungsten carbide coatings. These tungsten carbide coatings are common on the brake discs of high-performance cars. In this application, the tungsten carbide coating improves performance and maintenance intervals, while reducing brake dust.



One of the most important applications of tungsten carbide is the manufacture of tools for machining. These tools take advantage of the wear resistance and heat resistance of the material. They are usually used in situations where steel wears too quickly, such as high precision or mass production.



This material or its variants are also commonly used, such as tungsten carbide-cobalt composites in ammunition designed to pierce armor. The strength of tungsten carbide is also common in mining and foundation drilling. In sports, it is usually used as the tip of trekking poles or ski poles.



Sprayed tungsten carbide is usually used for jewelry wearing and surgical instruments. In the latter application, it provides better performance than stainless steel, but is more expensive and requires finer processing.
