Tungsten carbide powder, generally ranging in proportion between 70%-97% of the total weight, is mixed with a binder metal, usually cobalt, compacted in a die and then sintered in a furnace. Cemented Carbide may also contain proportions of Titanium Carbide (TiC), Tantalum Carbide (TaC) or Niobium Carbide (NbC).
material, are sintered alloys. WC-Co-based cemented carbide is widely used when cemented carbide is used as a cutting tool material. On the other hand, WC-Ni-based cemented carbide is hardly used for the cutting of other than non-ferromagnetic materials. This is the reason that WC-Ni-based cemented carbide is hardly used as a cutting tool material.

Sintering as used in powder metallurgy consists of mixing metal carbide powders having different melting points, and then heating the mixture to a temperature approximating the lowest melting point of any metal included. In sintered carbides, powdered cobalt, having the lowest melting point, acts as
With all the acronyms, abbreviations, and codes involved, stainless steel terminology might seem confusing. Whether you're looking for in-depth information related to engineering and metallurgy or you're simply looking for clarification on popular steel terms, our glossary offers a concise, approachable look at a range of common stainless steel definitions.
Sintering or frittage is the process of compacting and forming a solid mass of material by heat or pressure without melting it to the point of liquefaction.. Sintering happens naturally in mineral deposits or as a manufacturing process used with metals, ceramics, plastics, and other materials.
A Fe-Ni-Cu based matrix for diamond tools is designed for natural sintering, i.e. with a maximal sintering temperature of 1000 deg C. Dry mixing of the elemental powders is followed by a granulation step with an organic binder.

The excellent properties of high-temperature hardness and wear resistance of MITSUBISHI CARBIDE is obtained by sintering its main components, Tungsten Carbide, and a binder, Cobalt, having a low melting point using our high level powder metallurgy technology.In the production process, Tungsten Carbide is first produced, then Cobalt is added, and then compound materials are formed by pressing
The Designer's Guide to Tungsten Carbide This publication is a reference guide for designers, engineers, fabricators and end users of tungsten carbide material. It is a compilation of recommendations derived from practical experience, theoretical stress analysis, proven application engineering practices and modern manufacturing techniques.
Substantial progress in the development of the cemented carbide is due to Karl Schröter, who has discovered that the tungsten carbide powder mixed with metals such as iron, nickel and cobalt and compacted can be sintered with liquid phase, to give a product with a low porosity, very high hardness and considerable strength.Basing on the results
sintered at Vacuum and at a number of HIP sintering. A major portion of work is dedicated to determine the minimum sintering pressure to obtain low amount of early failures using TRS (Transverse Rupture Strength) tests. The work was initiated with four powder grades selection. The grades had different grain size and binder content and
In order to improve both the scratch strength and the micro-hardness of (Al,Cr)N coating film, the cathode material of an aluminum/chromium/tungsten target was used in adding the tungsten (W) to the cathode material of the aluminum/chromium target.
Sintered Silicon Carbide. InVinCer™ by Blasch Ultron™ Sintered Silicon Carbide(SSiC) is produced using very fine silicon carbide powder containing sintering additives. It is processed using forming methods typical for other ceramics and sintered at 2,200°C in an inert gas atmosphere.

Mar 27, 2012 · Electron Beam Evaporation a form of PVD in which the target anode is bombarded with an electron beam given off by a charged tungsten filament under high vacuum. The electrion beam causes atoms from the target material to transform into a gaseous phase, these atoms then return to solid form coating everything in the vacuum chamber with a thin film.
It is usually added in structural, tool, and spring tools. It is added as Ferro—vanadium. Tungsten:It is a strong deoxidizer. As an alloying addition it increases hardness, strength, and elasticity of steel. It is used in tool steels, high speed steels, cemented carbide alloys, etc. it is added as Ferro—tungsten.
