Properties, structure and application of sprayed tungsten carbide

       Sprayed tungsten carbide is a common metal coating in the metal manufacturing industry, with a series of characteristics such as corrosion resistance and wear resistance. Next, the thermal spraying manufacturer Yibai Precision will introduce some properties, structure and application of sprayed tungsten carbide.







What is Tungsten Carbide Spraying



Tungsten carbide is a fine powder, usually gray in color. Tungsten carbide powder can be sintered and pressed into jewelry, cutting tools or construction machinery parts.

However, if tungsten carbide is used in combination with a small amount of metal powder, tungsten carbide can be sprayed to 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 brittle ceramic material, it is mixed with cobalt, chromium, and nickel when used as a tungsten carbide coating. This metal-ceramic composite coating combines the ductility of metallic materials with the high hardness of ceramic tungsten carbide to achieve good performance.







Application of sprayed tungsten carbide



There are several potential applications for tungsten carbide, including thermally sprayed tungsten carbide coatings. This tungsten carbide coating is common in the brake discs of high-performance cars. Tungsten carbide coating improves performance and maintenance intervals and reduces brake dust.







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







This material or variants thereof are commonly used in the design of tungsten carbide cobalt composites in piercing armored munitions. The strength of tungsten carbide is also common in mining and foundation drilling. In sports, it is usually used as a material for trekking poles or ski poles.







Sprayed tungsten carbide is commonly used for jewelry wearing as well as surgical instruments. In the latter application, it offers better performance than stainless steel, but is more expensive and requires better handling.
