The physical and metallurgical properties of a particular "grade" of carbide are determined by its composition (its constituents and their relative amounts), the size distribution of the tungsten carbide grains after sintering, the binder metal type and content, the quality of the raw materials used, and the workmanship with which the material is made. Those most commonly measured to ...
If prepared with oxygencontaining tungsten compound, the final product must be carried out in vacuum processing 1500 ℃, to remove the carbon and oxygen compounds. Tungsten carbide is suitable to be machined at high temperature, and it can be made into cutting tools, structural materials of the furnace, drill bits for oil industry, jet engine parts, gas turbine parts, nozzles etc..
Tungsten Disulfide (WS2) can also be widely used in high temperature and high pressure fields. It offers temperature resistance from 450 deg F (270º C) to 1200 deg F (650º C) in normal atmosphere and from 305 deg F (188º C) to 2400º F (1316º C) in Vacuum. Load bearing ability of coated film is extremely high at 300,000 psi.

The objective of this study is to investigate the phenomenon of surface alloying by electrical discharge machining (EDM) process using tool electrodes manufactured by powder metallurgy (PM) process. Efforts have been made to find out the machining conditions that facilitate the transfer of desirable alloying elements (tungsten and carbon) to the machined surface.

Tungsten particles were collected by milling and screening the 325 mesh tungsten powder between 500 and 635 mesh sieves. Hot pressing of screened Cu powder was performed at 900 °C in Ar/4 %H2 atmosphere. XRD and ICP results show that the hotpressed Cu sample consists of about 5 vol% Cu2O, which is caused by the presence of oxygen on the surface of the starting Cu powder. Hot pressing the ...
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, armorpiercing shells and jewellery.
Microholes were machined with the same machining parameters by both tungsten and tungstencarbide electrodes. And, the same measurements and investigations were applied to these machined microholes with different electrodes. So, the effects of tungsten and tungstencarbide electrodes to EDM process, material removal rate and the hardness, surface roughness and heat affected zone of .
This specification is intended to assist welders in selecting and preparing one of the most important and frequently overlooked welding process variables: the tungsten electrode. Welders can spend thousands of dollars on welding equipment, but if they do not select and prepare their electrodes with this less expensive process component properly, then their welding results can be poor ...

Material Removal Processes • Machining is the broad term used to describe removal of material from a workpiece • Includes Cutting, Abrasive Processes (grinding), Advanced Machining Processes (electrical, chemical, thermal, hydrodynamic, lasers) • Automation began when lathes were introduced in 1700s • Now have computer numerical control (CNC) machines • Machining operations are a ...
Unalloyed tungsten tube are produced from pure tungsten powder, without extra additive. The purity is usually quite high, %. Compared with alloyed tungsten, pure material is easier to be processed as pure tungsten could be worked by forging, drawing or extruding. Pure tungsten blanks, which are made from tungsten powder by powder metallurgy, are the raw material to process W tube.
In our past article, we provided an overview of the material known as Tungsten this follow up, we''ll tell you how this key material is made. Tungsten has the highest melting point of all metals, at 3410 o C (6170 o F). In order to create parts made from tungsten or tungsten alloys like tungsten carbide, the typical process of melting and blending of the metal and alloying elements ...
The sintering process causes the tungsten carbide and cobalt matrix to fuse together to produce a dense "Hard Metal". After sintering the material is so hard that it can only be machined by diamond grinding, a specialised form of micro machining that is relatively expensive as it is not possible to remove large amounts of materials by this process.
