Indentation Damage in Tungsten Carbide and Tungsten-Titanium Carbide

1983
Tungsten carbide (WC) is the main constituent of cemented carbides used for metal machining and rock drilling. Titanium carbide (TiC) is added to some grades of WC-Co to improve wear resistance in cutting metals. These grades contain both hexagonal WC and cubic (W, Ti)C solid solutions as the principal hard phases.

Synthesis of Tungsten Carbide Nanomaterials in Triple DC Thermal Plasma Jet System.

Journal of Nanoscience and Nanotechnology, 2019
The tungsten carbide nanomaterials were synthesized in the triple DC thermal plasma jet system using refractory tungsten, and carbon sources such as multi wall carbon nanotube (MWCNT), amorphous carbon and methane.

Stoichiometric tungsten carbide coatings

AIP Conference Proceedings, 1996
Filament Assisted Chemical Vapor Deposition (FA‐CVD) technique has been used to prepare tungsten carbide (WC) thin films. With this simple technique we obtained polycrystalline and stoichiometric WC coatings deposited on crystalline silicon and on stainless steel substrates.

Tungsten Carbide and Tungsten-Molybdenum Carbides as Automobile Exhaust Catalysts

1987
Several catalyst samples of tungsten carbide and W,Mo mixed carbides with different Mo/W atom ratios, have been prepared to test their ability to remove carbon monoxide, nitric oxide and propane from a synthetic exhaust gas simulating automobile emissions. Surface characterization of the catalysts has been performed by X-ray photoelectron spectroscopy (

Three-component fermions with surface Fermi arcs in tungsten carbide

, 2017
Topological Dirac and Weyl semimetals not only host quasiparticles analogous to the elementary fermionic particles in high-energy physics, but also have a non-trivial band topology manifested by gapless surface states, which induce exotic surface Fermi ...

Cohesion in tungsten carbide

Materials Science and Technology, 1995
AbstractA recent method for analysing the cohesion of transition metal carbides is applied to the carbides of tungsten. In the most interesting of these, WC, the W atoms are not close packed but are arranged in a simple hexagonal sub lattice of lower coordination number.

High-Strength Tungsten Carbides

1971
It is well known1,2 that the mechanical properties of sintered tungsten carbide-cobalt alloys are critically dependent upon carbon content. Only when the carbon content corresponds closely to the theoretical value for WC, i.e. 6.13 weight %, are two-phase structures (WC and a Co-rich solid solution) observed.
