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.

On the plasticity of tungsten carbide

Physica Status Solidi (a), 1973
Tungsten carbide (WC) is known to have mechanical properties different from the other refractory carbides. WC-grains in a cemented carbide grade containing 15% Co were studied by transmission electron microscopy. Dislocation networks specific to WC were found.

Development of an electrochemical sensor based on a functionalized carbon black/tungsten carbide hybrid composite for the detection of furazolidone

New Journal of Chemistry, 2019
In this study, the simple sonochemical synthesis of functionalized carbon black (f-CB) anchored with tungsten carbide (WC) is used to prepare a novel electrocatalyst for the electrochemical detection of furazolidone (FU) by modifying screen-printed ...

Investigating the micropitting and wear performance of copper oxide and tungsten carbide nanofluids under boundary lubrication

Wear, 2019
The potential of copper oxide (CuO) and tungsten carbide (WC) nanofluids in enhancing micropitting and wear behavior of AISI 8620 steel under boundary lubrication conditions was investigated.

Nanocrystalline Tungsten Carbide

2013
In this chapter, attention will be given mainly to the production methods and investigation of particle size, microstructure and some properties of powders of tungsten carbide WC with a particle size from 20 to 200–300 nm, i.e. nanocrystalline and submicrocrystalline powders. Using an X-ray diffraction method for determining small particle size will be

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 (

Surface Electronic Properties of Tungsten, Tungsten Carbide, and Platinum

Science, 1974
The local electronic structures of the surface regions of tungsten, tungsten carbide, and platinum have been compared. Contrary to the hypothesis that the platinum-like catalytic activity of tungsten carbide results from the contribution of carbon valence electrons to the 5 d band of tungsten, the width of the ...
