tucadur® 2020 Tungsten Carbide Coating Unit 8 Use The unit is used to apply tungsten carbide layers to meta llic surfaces. The tungsten carbide layer (up to 40 µm thick) increases wear resistance of the coated workpiece, without affecting the properties of the base material. Applications: for working examples, refer to appendix 12.
The more often your power plant shuts down to replace worn parts, the further behind production falls and scheduling is disrupted. Kinton Carbide supports the power generation industry with superior wear resistant components. Within the harshest abrasion and erosion environments, bonded tungsten carbide and ceramic tiles are the solution.
Tungsten Carbide - an overview | ScienceDirect Topics
5.3 Tungsten Carbide. Tungsten monocarbide is the most important commercial tungsten carbide. It forms the basis for the whole cemented carbide industry, which produces a large array of dies, cutting tools, drills, etc. Cemented carbides are composites of the hard grain or powder bonded by a metal phase, typically cobalt.
Silver Tungsten EDM Electrodes. When most people think electrical discharge machining, they think brass, copper, and maybe tungsten carbide electrodes. These three materials are ideal for the great majority of EDM applications, and it’s not often that customers ask for anything else. But sometimes the unique requirements of an EDM job require ...
Silver-tungsten is an electrode material with a niche application in electrical discharge machining (EDM). A metal matrix composite composed of silver infiltrated into a tungsten carbide matrix, silver-tungsten combines the drilling power of tungsten carbide with the exceptional conductivity of silver.
Electrodes used for drilling in electrical discharge machining, in brass, copper, tungsten carbide, copper-tungsten, silver-tungsten, and molybdenum. EDM Drill Electrodes. Electrical discharge machining (EDM) erodes material through sparking, and it uses electrodes to do this. And just as sparking erodes a workpiece, it erodes the electrode itself.
The advantages of brass, copper, tungsten carbide, copper-tungsten, silver-tungsten, and molybdenum electrode rods. In electrical discharge machining, rods are a rarity. The importance of flushing and cooling make tubular electrodes a necessity for most applications, relegating the use of rods to niche applications.
At General Carbide, we manufacture semi-finished tungsten carbide tooling for rotary knives and anvils to meet your particular cutting requirements. We can produce tools with diameters up to 330mm (13\") with common edge, or with segmented cutting edge designs.
High Voltage Electric Discharge Consolidation of Tungsten ...
WC–Co composites are extensively used to enhance the wear resistance of various engineering components, e.g. cutting tools and dies. In this paper, we report the results of studying the macroscopic phenomena occurring under high voltage electric discharge consolidation of tungsten carbide - cobalt powder (Grigoryev & Rosliakov, 2007).

Pal and Partha Saha, Soft computing models based prediction of cutting speed and surface roughness in wire electro-discharge machining of tungsten carbide cobalt composite, The International Journal of Advanced Manufacturing Technology, 10.1007/s00170-007-1200-z, 39, 1-2, (74-84), (2007).
Micro Grinding Blind Holes in Hard Tungsten Carbide with ...
using tungsten carbide compound workpieces, HC US10 from Hydro Carbide. Two faces of two tungsten carbide blocks (25×25×12mm) are polished ﬂat and then wrung together with a lateral oﬀset. The blockss are clamped together, and the end of the composite workpiece is ground to provide a ﬂat surface perpen-dicular to the hole axis.
Electrical discharge machining is favored over other machining methods because it makes drilling into very touch materials possible. In most applications, brass and copper provide all the penetrative power necessary to finish a hole. But sometimes brass and copper electrodes fall short. It is in these situations that tungsten carbide is used.
High Voltage Electric Discharge Consolidation of Tungsten ...
High Voltage Electric Discharge Consolidati on of Tungsten Carbide - Cobalt Powder 349 We determined the density change of consolidated sample versus time by using high-speed movie recording. To study the consolidation kinetics, we used a high-speed SKS-1M camera, which makes it possible to record movies with a frequency up to 4×10 3 frames/s.
Tungsten Carbide Core Bits Tungsten-Carbide Set Core Bits. This type of bit uses seismic grade tungsten-carbide as the cutting media. Tungsten-carbide does not possess the hardness of diamond and as such has a limited range of application as a core drilling cutting media.
Electrode Supplies. Holepop EDM Supplies & Electrodes is a specialty distributor of electrode drills used in EDM small hole drilling. Our electrodes are available in brass, copper, tungsten carbide, copper-tungsten, and silver-tungsten, all materials with unique capabilities.
Making the Tungsten Carbide Raw Material. When a mixture of powdered tungsten metal and carbon powder are raised to a very high temperature by an arc of electricity, while the whole mass is held in a carbon crucible, there is a complete chemical combination of the two elements to form a big lump of tungsten carbide ( WC ).
Performance of Difference Electrode Materials in ...
tungsten carbide is 2,800°C. Due to its properties, it cannot be processed easily by conventional machining technique (Singh et al ., 2004). So EDM process will open up an opportunity for the machining of tungsten carbide. Tungsten carbide is some kind of cemented carbide; the particle of carbide is bind with the process
Tungsten carbide electrodes for electrical discharge machining shipped from the US to all over the world. Tungsten Carbide Electrodes. Electrical discharge machining (EDM) is a popular machining method, valued for its ability to drill into extremely robust alloys used in industries such as aerospace, defense, energy, and biomedical engineering. ...
Tungsten Carbide Decarburization by Electrical Discharges
Electrospark deposition (ESD) was employed to clad WC-10%Co hard alloy on steel 1035 and the tribological properties of the coatings obtained were examined. The influence of the duration and frequency of discharges, the nature of the environment, and the carbon concentration in the electrode materials on the decarburization of tungsten carbide was studied.
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments ...
Tungsten Carbide Coating - Tungsten Carbide Powder | NAS
Tungsten carbide coating is done through a process known as High-Velocity Oxygen Fuel spraying (HVOF). This tungsten carbide coating process involves the use of combustive thermal spray at high velocity to develop exceptional wear and corrosion resistance. It is by far the most preferred method of coating owing to the many benefits it presents.
Tungsten carbide is a very tough material made up of tungsten and carbon atoms. Its principal component, tungsten (wolfram), is one of the densest non-radioactive elements, and has the highest melting point of any element.
