Tungsten carbide (AKA sintered, cemented carbide) is one of the most important modern tooling material manufactured by a process of powder metallurgy. Substantial progress in the development of the cemented carbide is due to Karl Schröter, who has discovered that the tungsten carbide powder mixed with metals such as iron, nickel and cobalt and compacted can be sintered with liquid phase, to give a product with a low porosity, very high hardness and considerable strength. Basing on the results of his work cemented carbides consisting mainly of tungsten carbide, were patented in 1923. Currently, it is a composite of tungsten carbide combined with cobalt or nickel matrix, and sometimes other additives such as tantalum , niobium, titanium.
No i w sumie nie wiem, jak na to patrzec...
