Tungsten Powder Metallurgy - Sintering is commonly regarded as taking place in three stages： *During the early stage, necks are formed between individual particles and grow by diffusion, increasing the interparticle contact area. The powder aggregate shrinks, involving center to center approach of the particles.
During sintering some of the cobalt in the cemented carbides will alloy with either carbon or tungsten carbide. Therefore the carbon imbalance of the sample will affect the Coercivity. For Coercivity it is important to know the metallurgical condition of the sample in terms of free carbon, normal or Eta-phase, as these will affect the
Graphite sintered container is made of high quality artificial graphite by mechanical processing. It is mainly used in all kinds of vacuum resistance furnace, carbon tube furnace, induction furnace, sintering furnace, brazing furnace, ion nitriding furnace, tantalum niobium smelting furnace, vacuum quenching furnace and so on, of which need graphite plate, graphite boat, graphite heater
Ceramic and Metal Carbide Sintering: One Step debiding and sintering Process in a single chamber for Metals and Ceramics. Ready to use recipe loaded in built for selected metal and Ceramics. Capable to sinter Sic and BN - high Temperature ceramics and WC - Tungsten Carbide Alloy sintering.
Vacuum Sintering Furnace. Vacuum sintering, refers to the process that making the powder material into dense material in the condition of the vacuum.People use this process to produce ceramics, powder metallurgy, refractories, ultra-high temperature materials.
inch at the brazing temperature. Vacuum has an effect on the design of clearances for a specific base and filler material. Vacuum brazing requires lower clearances than atmospheric type brazing to obtain optimum strength in the joint. In general, in vacuum furnace brazing of a vertical joint, a free

Description 10MPa sinter-HIP furnace is well-suited for pressure sintering of cemented carbide and precision ceramic. We can design this 100bar gas pressure sintering furnace as per your product's particular temperature, time and atmosphere requirements, rather than just offering standard sintering furnace models, so you don't need to modify your process to fit them.
PVA Industrial Vacuum Systems GmbH manufactures furnaces for sintering metals, non-oxide ceramics, cermets, or cemented carbides, which receive particular attention at PVA. Cemented carbides are sintered in the liquid phase, whereby the metal binder contained in the pellet—usually cobalt—is used for melting and binds the cemented tungsten
Vacuum sintering furnace can be customized according to customers'requirements. Application of vacuum sintering furnace: Vacuum sintering furnace is mainly used in sinter cemented carbides, stainless steel line molding, stainless steel fiber, magnetic materials,and ceramic materials,and it also can be used in power metallurgy, refractory metals and magnetic material industry.We can sinter
The vacuum sinter is to put the tungsten carbide products in the vacuum sinter furnace for sintering, when it gets the sintering temperature, the sample's shrinkage reduces greatly with the increase of the holding time, which means the shrinkage for the sample is finished in the stage of vacuum sintering .Later,it make an apparently shrink to
The RED DEVIL™ furnace consumes little power--less than 2 kilowatts--and operates from a standard 20 amp wall outlet. A typical run at full temperature can be made at a utility cost of less than one US dollar. The RED DEVIL™ high temperature sintering furnace is an ideal choice for researchers interested in simple and efficient vacuum
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
Toonney Carbide Bar Plant own workshops which covers an area of about 8,000 square meters, a total of 3 floors, is equipped with latest technology level production lines, can obtain cemented tungsten carbide products such as tungsten carbide rod, perform, carbide blank etc. from tungsten carbide and cobalt powder.
The tendency of refractory metals to oxidize requires reducing atmospheres or vacuum for sintering. Tungsten, Mo and Re are often sintered in hydrogen with a dew point below − 20 °C. Iridium and Ru have less tendency to oxidize, so vacuum sintering is usually suitable.
