Cemented carbide is a hard material used extensively as cutting tool material, as well as other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of
Mar 31, 2012 · When choosing a Tungsten Carbide Powder, the particle size and type of carbide selected are important in determining the correct material to combat various forms of erosion, abrasion and wear. Whereas the amount of metal matrix in the coating (nickel, cobalt, or alloy) will depend on the toughness and abrasion resistance required.

succeeded in the test production of a cemented carbide History of Development of Cemented Carbides and Cermet Keiichi TSUDA-----Cemented carbide was first commercialized by our company in 1928 for use in wire drawing dies. It has since been developed as a base material for cutting tools.
August 2008 - Federal Carbide completes the installation of the most advanced sinter-HIP furnace in the world for the sintering of cemented tungsten carbide products. Further expanding its carbide sintering capabilities, Federal Carbide will place into service a new 12.5 cubic foot working capacity sinter-HIP furnace in August.

Vacuum Furnace for Tungsten Carbide scrape recycling furnace /sintering furnace Description PT-V series vacuum furnace is widely used for heat treatment of metal materials in high vacuum,recursive,protective atmosphere,also used for heat treatment of special materials,such as carbonation process of carbon products development.
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).
FIELD: heating system.SUBSTANCE: contact surface of the heat exchanger is pre-coated with a layer of high vacuum oil, the heat exchanger is placed in a sintering container, the container is filled with copper balls with a size of 100 to 500 mcm, the copper balls that have not adhered to the high-vacuum oiled surface are poured from the said container and poured into a sintering container With
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.
The furnace has a maximum operating temperature of 1315°C and the dual load car design has the capacity to transfer up to 68 tonnes of material in and out of the furnace. The state of the art

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
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.
The metallurgical bonding of the substrate with coating from cemented carbide is generated due to mutual diffusion of Fe towards coating and W, Co, Ni towards substrate. 4. The Wear resistance for coating from cemented carbide by vacuum powder sintering is excess over that for high speed steel due to multi-strengthening mechanism.

14.2.1 Cemented carbides. Cemented (or sintered) carbides, known collectively in most parts of the world as hard metals, are a range of very hard, refractory, wear-resistant alloys made by powder metallurgy techniques. The minute carbide or nitride particles are cemented by a binder metal that is liquid at the sintering temperature.
What is "Sintering or Sinter-HIPing"? Sintering is the process in which the tungsten carbide grains are fused into the cobalt matrix by heating the green material (carbide that has not been sintered is called green) to a high temperature.
