Tungsten carbide Usage And Synthesis
Physical propertiesTungsten carbide is a dense, metal-like substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600º C (4,700º F). Tungsten carbide has very high strength for a material so hard and rigid. Compressive strength is higher than virtually all melted and cast or forged metals and alloys; and is two to three times as rigid as steel and four to six times as rigid as cast iron and brass. High resistance to deformation and deflection is very valuable in those many applications where a combination of minimum deflection and good ultimate strength merits first consideration. For such a hard material with very high rigidity the impact resistance is high because it is in the range of hardened tool steels of lower hardness and compressive strength. It also performs well up to about 1000°F in oxidizing atmospheres and to 1500°F in non-oxidizing atmospheres; it undergoes no phase changes during heating and cooling, retains its stability indefinitely; and retains toughness and impact strength in the cryogenic temperature ranges. (-453°F.)
Tungsten carbide
Tungsten carbide has exceptional resistance to galling and welding at the surface, and has sufficient resistance to corrosion-wear conditions for many applications. Tungsten carbide wears up to 100 times longer than steel in conditions including abrasion, erosion and galling. Wear resistance of tungsten carbide is better than that of wear-resistance tool steels.

PreparationTungsten carbide is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400º1,600º C (2,550º-2,900º F). For fabrication, a process developed in the 1920s is employed: the powdered tungsten carbide is mixed with another powdered metal, usually cobalt, and pressed into the desired shape, then heated to temperatures of 1,400º-1,600º C; the other metal, which melts, wets and partially dissolves the grains of tungsten carbide, thus acting as a binder or cement. The cemented composites of tungsten carbide-cobalt are known by many different trade names, including Widia and Carboloy.
Chemical PropertiesGray powder. Mohs hardness of 9+ in solid form. Insoluble in water but readily attacked by a nitric acid– hydrofluoric acidmixture. Stable to 400C with chlorine, burns in fluorine at room temperature, oxidizes on heating in air.
UsesTungsten carbide is extremely hard and are excellent cutting materials. It is used extensivly in the tool and die industry for drilling and cutting tools, sand blasting nozzels, armor-piercing bullets, and studs to increase traction of tires.
Besides, it is used in dental burs, surgical instruments, wear-resistant coatings; in manufacture of cemented carbide; Substitute for noble metals in catalysis.
UsesTungsten Carbide/Carbon (WC/C) is a black-gray colored coating of hard tungsten carbide particles in a soft amorphous carbon matrix. It is used for precision components with abrasive and adhesive wear, seizure problems (poor lubrication) and for dry machining applications.
DefinitionA black powder,WC, made by heating powderedtungsten metal with lamp black at1600°C. It is extremely hard (9.5 onMohs’ scale) and is used in dies andcutting tools. A ditungsten carbide,W2C, also exists.
DefinitionA ditungsten carbide, W2C, with similar physical properties is also known. WC is said to be the strongest of all structural materials.
HazardToxic by inhalation.
Industrial usesTungsten carbide with a 3 to 20% matrix ofcobalt is the most common structural RHM. Thelow-cobalt grades are used for applicationsrequiring wear resistance; the high-cobalt gradesserve where impact resistance is required.
Safety ProfileChronic inhalation causes lung damage in humans. Ignites at 600°C in nitrogen oxide atmospheres. Violent reaction with F2, ClF3, NOx, IF5, PbO2, NO2, N20. See also TUNGSTEN COMPOUNDS.
