What is a cemented carbide?

cemented carbide is a particularly hard metal that is known to be able to handle hard materials, fast machine speed and high temperature. The material is also known as harmful, widia ™ or tungsten-carbide cobalt. It is often used in the production of objects such as stainless steel or carbon steel. These materials are connected together in a process known as salivation or less commonly hot isostatic pressing (hip), where the molten cobalt is mixed with solid grains of tungsten carbide. The strength and durability of the final product can vary very much depending on the amount of each component in the mixture. Although cobalt provides additional durability, tools made of this Motherial is still prone to breaking or cleavage. A more robust metal such as carbon steel is often used as a stem into which carbide tip can be inserted. This can reduce the costs of both reducing the total cost of the tool and the cost of replacing carbide.

carabide liners can also be reinforced with special coatings such as titanium carbid-nitride, titanium aluminum nitride or diamond carbon. These coatings can help increase tool lubrication. The coating can also extend the lifetime of the liner by lowering the temperature during cutting, thereby reducing it back to wear.

The first cemented carbide was developed at the end of the 18th century by French chemist Henri Moissan. Moissan decided to create diamonds, but his experiments led to the development of a porous, fragile version of modern tungsten carbide. The Germans Karl Schroeter and Heinrich Baumhauef found that the material can be stronger and more suitable for industrial uses such as cutting, adding cobalt

Commercial use of cemented carbide began in Germany at the end of the 1920s. The pioneering brand was Widia ™, a version of Wie diment , a German phrase that means "like a diamond". This brand lasted as a general term for a cemented carbide.

In the 1930s, the replacement of tungsten carbide was helped by a tantal carbide and metal nickel mixture to create a more durable form of cemented carbide. Now the material is made of several different variations of traditional and modern mixtures. One constant was that the mixture usually consists of one part of the molten material connected to the grains of another element.
