The invention is directed to a method for polishing a surface comprising tungsten carbide, comprising contacting a surface comprising tungsten carbide with an oxidizing agent, a polishing component, and a liquid carrier, and abrading at least a portion of the surface to polish the surface. The invention further provides a method for reconditioning a workpiece comprising tungsten carbide.
As we know, very heavy metals like lead floats on the surface of mercury. But will tungsten carbide float on mercury? We discuss specific gravity (dens...
In this work the surface of ductile iron is hardened by a tungsten carbide (WC) layer. The inserted layer is obtained by pouring liquid cast iron on a mixture formed by WC particles (with an ...
Tungsten carbide (WC/W 2 C) materials, often in a cobalt matrix, offer the best wear protection. For service that requires better corrosion resistance, we recommend a matrix of nickel-cobalt-chromium (NiCoCr), or cobalt-chromium-nickel (CoCrNi). If your application requires service temperatures above 500 °C (930 °F), we recommend chromium ...
1923: A German electrical bulb company submits a patent for tungsten carbide, or hardmetal. It's made by "cementing" very hard tungsten monocarbide (WC) grains in a binder matrix of tough cobalt metal by liquid phase sintering. The result changed the history of tungsten: a material which combines high strength, toughness and high hardness.

Tungsten carbide powder is the base for the production of cemented carbides, the vast class of hard, wear resistant, refractory materials in which the hard carbide particles are bound together, or cemented, by a soft and ductile metal binder. Conventional manufacturing of tungsten carbide powders accounts world-wide for the bulk of the tungsten ...
Tungsten Carbide Hardfacing will reduce eductor wear and increase the eductor's service life. The higher cost of tungsten carbide-clad parts stems from the manufacturing process. Basically, the process starts with a 'substrate'–for example, a cast and/or machined raw body with metallurgical properties to optimize cladding.
The results showed that the tungsten carbide powder emerged well in the cellulose matrix as an inert densifier. The composite beads had a spherical appearance, a suitable size and size distribution, an appropriate wet density of 1.32–1.68 g/mL, a porosity of 90–96%, a pore radius of 45–65 nm, and a specific surface area of 30–42 m 2 /mL.
Cobalt is the most widely added binder or 'cement' in cemented tungsten carbides due to its function to wet tungsten carbide grains on the process of liquid phase sintering. So, cobalt is considered to be superior to other binder when it comes to eliminating residual porosity and gaining high strength and toughness properties in sintered ...
An attempt was made to coat graphite fibers with tungsten carbide. Solid and liquid copper were used as a diffusion medium for tungsten to migrate to the surface of the graphite fibers at elevated temperature to form carbides. It was found that it is possible to electroplate Cu-1 pct W alloy on graphite fibers. It was established that this alloy contained tungsten in atomic dispersion. It was ...
Tungsten carbide is a homogenous mixture of tungsten carbide grains in a tough cobalt binder matrix. The carbide grains are fused into a solid matrix of cobalt metals. The metal carbide's grains are "cemented" in the binder metal's matrix. The fusion process is called liquid phase sintering, or …
