Tungsten Carbide Thermal Spray | Tungsten Spray Coatings
Tungsten carbide coatings are achieved through the HVOF thermal spray process. Within this process, fuel gas and oxygen are combusted in a high-pressure chamber reaching temperatures up to 5,600°F (3,093°C). The resulting hot, high-pressure gas is ejected through a small-diameter nozzle and accelerated down a long barrel at supersonic speeds.

Tungsten Carbide | Density, Strength, Hardness, Melting Point
Melting point of Tungsten Carbide is 2867 °C. Note that, these points are associated with the standard atmospheric pressure. In general, melting is a phase change of a substance from the solid to the liquid phase. The melting point of a substance is the temperature at which this phase change occurs. The melting point also defines a condition ...

CERATIZIT | Production
The manufacturing process of tungsten carbide starts with the mining of the tungsten ore. In the first separation and processing steps a very pure crystallised product, ammonium paratungstate (APT) is produced. Annealing in vacuum then results in the blue tungsten oxide W2O5, annealing in air produces the greenish yellow tungsten oxide WO3.

Tungsten carbide | hardness, strength, durability | Britannica
Tungsten carbide is a dense, metallike substance, light gray with a bluish tinge, that decomposes, rather than melts, at 2,600° C (4,700° F). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400°–1,600° C (2,550°–2,900° F). For fabrication, a process developed in the 1920s is employed: the powdered …
