Cemented carbide represents a class of composite materials, consisting of hard and wear resistant carbide and a tough and ductile metal binder, and thus owns a unique combination of hardness and toughness. In order to increase the performance and extend the service lifetime of the cemented carbides, graded cemented carbides have been developed.
Tungsten carbide From Wikipedia, the free encyclopedia Tungsten carbide (chemical formula: WC) is an inorganic chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes for use in industrial
2019-4-1 The most industrially used gradient cemented carbide is the γ-phase free gradient. The main benefit of γ-phase free gradients (thickness: 10-30 μm) is the increased toughness in the surface layer. In cemented carbides coated with CVD it is necessary to prevent the propagation of thermal cracks formed in the coating during the cooling step of

2002-1-21 Cemented Carbide. At present, tungsten in the form of tungsten carbide is mainly used in the production of cemented carbide. Cemented carbide, (also referred to as hard metal), is a material created by “cementing” very hard tungsten monocarbide (WC) grains in a binder matrix of tough cobalt metal, using the liquid phase sintering process.
2020-10-15 Historically referred to as Wolfram, Wolf Rahm, wolframite ore discovered by Peter Woulfe was then later carburized and cemented with a binder creating a composite now called "cemented tungsten carbide". Tungsten is Swedish for "heavy stone". Colloquially among workers in various industries (such as machining and carpentry), tungsten carbide is often simply called carbide, despite

2018-5-1 As shown in Fig. 2, in the quenched cemented carbide with addition of VC, the complexions are observed distributing on the WC (0001) and WC (10-10) planes at WC/Co interfaces, which have a morphology of nanofilm and a fcc structure. The STEM-EDAX analyses in Fig. 2(b) and (c) indicate that there is a little higher V concentration at the WC/Co interface than that inside the phases, implying

2021-1-16 Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate.

2019-2-22 Cemented tungsten carbide (WC) is commonly used for wear-resistant applications, such as cutting tools and abrasives due to its extremely high hardness. This hardness leads to post-process machining of WC to be time- and cost-intensive. This study examined the feasibility of additive manufacturing of cemented WC to near-net-shape in an effort to reduce post-process machining. The
