For the first time, the formation of coatings by detonation spraying (DS) of a binder-free tungsten carbide, WC, was studied. The coating phase composition was shown to depend on the O/C molar ratio in the oxygen-acetylene mixture used for the spraying. Along with WC, cubic carbide/oxycarbide WC1-xOy, tungsten semicarbide …

Greil [35] shows that during sintering of tungsten carbonitride and tungsten carbide powder, produced at the same reaction temperature from W + C mixtures lead to different grain sizes of WC in sintered state (10 wt% Co). The basis for this development is the already smaller grain size of the carbonitride particles compared to the tungsten ...
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 ...

The 10 g of low-grade tungsten carbide was loaded in a 40 mm ID of tubular alumina reactor and dried at 200 °C for 2 hours with helium gas. The decarburization and oxidation of the LWC was performed with CO/CO 2 mixtures with the ratio of 1/9 to 7/3 in the temperature range of 600 ~ 1000 °C under atmospheric pressure.
Properties of Tungsten Carbide. Tungsten 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). It is prepared by heating powdered tungsten with carbon black in the presence of hydrogen at 1,400o-1,600o C (2,550o-2,900o F). For fabrication, a process developed in the ...
Cutting tools. Abrasive materials. Wear-resistant coatings. Refractory materials. 3. Boron Carbide. Boron carbide is made up of boron and carbon atoms. Like silicon carbide, it's classified as a metalloid and ranks between 9 and 10 on the Mohs hardness scale, making it one of the hardest known materials in existence.
The addition of Li2CO3 (4.5 wt.%) to the electrolytic salt mixture decreased the tungsten carbide particles to 10 nm, changed their morphology, and increased the free carbon content in the composite up to 5 wt.%. The specific surface area of the powder increased by a factor of 4 to 7 (from 20–35 to 140 m2/g).

The grade K44UF is made of .5 µm tungsten carbide powder and contains 12 percent cobalt. While the toughness of both grades is approximately the same, the Vickers hardness of K44UF is 5 percent ...
Tungsten already has a large elastic modulus, one larger than most steels; tungsten carbide has an even greater elastic modulus, showing its impressive rigidity. Generally, materials stiffness correlates with a large elastic modulus, and the values shown in Table 1 prove why tungsten carbide is second only to diamond in elastic resilience.
