Tungsten carbide is a chemical compound with the formula WC. It is an extremely hard material that is used in a variety of industrial applications, including mining and drilling. Tungsten carbide can be used in powdered, granular form for coatings, in large, crushed particles or agglomerations of very fine tungsten carbide dust, or it can be ...
nThe sintered and crushed carbide hard phase used in Metco 36C, WOKA 7703 and WOKA 7705G results in tungsten carbide grains that are larger, more angular in shape and with higher apparent density. These carbides exhibit better distribution in the matrix with less dissolu-tion, resulting in reduced coating brittleness and a lower tendency to crack.
On account of the reason above, considerable studies have paid overwhelming attention to the development of BTC. As pioneered by Kanemitsu [] in 1982, BTC, also named binderless cemented carbide, is tungsten carbide free of any metallic binder including cobalt, iron, and nickel.As shown in Fig. 1, because of the absence of …
Tungsten is a chemical element with the atomic number 74 and symbol W. It is a dense, grayish-white metal that is extremely hard. Tungsten has the highest melting point and boiling point. Tungsten is a hard metal that ranks between 7.5 and 8 on the Mohs hardness scale. However, tungsten carbide is much harder than tungsten.
