Powder metallurgy-or PM-is a state -of-the-art metal-forming process used to produce net-shape components. Made by mixing elemental or alloy powders and compacting the mixture in a die, the resultant shapes are then sintered (heated) in a controlled-atmosphere furnace to bond the particles metallurgically.
200591Dennis Tool has developed commercial microwave sintering furnaces since 1996, as well as several tungsten carbide products with enhanced properties due to the microwave sintering process. This worked stemmed from an agreement with the Penn State Research Foundation to further develop and commercialize this technology.
92WC-8 Co powder mixture with superfine-tungsten carbide was respectively sintered by spark plasma sintering(SPS) and sintering isostatic pressure (SIP). Complete dense samples with 200 nm WC grains and 94.2 HRA hardness were prepared by spark plasma sintering at 1 150 °C and under 4.5 kN for 5 minutes.
200982How is Hard Metal or Tungsten Carbide Made? Tungsten Carbide Hard Metals are primarily produced using a Powder Metallurgy process, whereby the powdered forms of tungsten carbide and cobalt are mixed using ball mills, a binder material is added to hold the powders together during the next stage of the process which is compaction or pressing.
20151117Hydrogen Furnace Sintering is used widely as part of many powder metallurgy (PM) processes to create parts of extremely accurate size and uniformity. Stainless steel is common, but a other high-performance alloys, such as tungsten carbide and other alloys, also require high-temperature sintering in hydrogen.
2018725The fuzzy control is superior to the traditional PID control and can meet the control requirements of the vacuum sintering furnace temperature of powder metallurgy. The vacuum sintering furnace of powder metallurgy is a time - varying, hysteresis and nonlinear heating system.
Powder particle size and size distribution Particle size of metal powder is expressed by the diameter for spherical shaped particles and by the average diameter for non-spherical particle as determined by sieving method or microscopic examination. Metal powders used in powder metallurgy usually vary in size from 20 to 200 microns.
1. Sintering furnace can be used to sinter ceramic powder, ceramic ferrule and other zirconia ceramics. 2. Sintering furnace can be used to sinter diamond saw blade, carbide rods, carbide cutting tools and so on. 3. Sintering furnace can be used as heat treating of copper and steel belt. 4.
The process was: pressing tungsten powder bars, pre-sinterizing them in a hydrogen atmosphere to make them harder, and then sintering them with carbon electrodes cooled with water in a hydrogen oven, with a temperature close to that of tungsten's melting point.

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
Silicon carbide sintering furnace is a batch induction heating furnace, mainly used for producing tungsten carbide powder, titanium carbide powder, vanadium carbide powder and composite metal powder of various sizes in cemented carbide and powder metallurgy industries.
Powder metallurgy is also used to make unique materials impossible to melt or form in other ways. A very important product of this type is tungsten carbide (WC). WC is used to cut and form other metals and is made from WC particles bonded with cobalt. It is very widely used in industry for tools of many types and globally ~50,000t/yr is made by PM.
same sintering process as tungsten lamp wire was not successful. The eventual addition of a cobalt and iron metal powder binder was needed to get an adequate result from the sintering process . Powder metallurgy is still the predominant process used to create these cermet materials,
facturer Osram GmbH. invented cemented carbide as a composite material in which tungsten carbide (WC) was the hard phase and cobalt (Co) was the binder. This signified the emergence of powder metallurgy products produced by blending WC powders with Co powders and press-molding it, followed by sintering at a high temperature.
