Tungsten carbide is a commonly used material for precision engineering due to its high degree of hardness, high Young's modulus, high wear resistance, high thermal conductivity, and excellent thermal and dimensional stability. Thin film coatings of tungsten carbide have been successfully applied onto the running surfaces of precision linear ...
Besides metallic bonding between tungsten atoms, extremely strong covalent bonding between tungsten and carbon is crucial for the physical properties. The exact carbon content of 6.13 wt% requires ultimate precision in carbon control during WC manufacture to avoid the presence of free carbon or sub carbide phase.
Tungsten carbide, or "carbide" as it is often historically referred to, is a compound composed of one atom of tungsten and one atom of carbon. Tungsten carbide synthesis has been covered previously in several comprehensive books over the years (Brooks, 1996; Lassner & Schubert, 1999; Yih & Wang, 1979). In this chapter, we cover the basics and ...
Tungsten exists industrially in multiple forms including tungsten metal, tungsten carbide (equal parts tungsten metal and carbon) and tungstate. Tungsten metal or tungsten carbide is often found to exist industrially as an alloy with other metals including cobalt, nickel, and iron ( Kraus et al., 2001 ; Roedel, Cafasso, Lee, & Pierce, 2012 ...
Tungsten carbide powder is the base for the production of cemented carbides, the vast class of hard, wear resistant, refractory materials in which the hard carbide particles are bound together, or cemented, by a soft and ductile metal binder. Conventional manufacturing of tungsten carbide powders accounts world-wide for the bulk of the tungsten ...
In commercial tungsten carbide alloys with a relatively fast cooling rate, the presence of M 6 C is more probable than that of M 12 C [112]. The level of carbon deficiency in the system and the cooling rate will greatly influence the amount and shape of the eta-phase in the alloy.
