Linde features 'Best Practice' in sintering for improving . By establishing a carbon-neutral atmosphere during sintering, MIM parts avoid decarburization, a frequent problem that prevents the carbon content from being in specification.
Sintering is done in a sintering furnace or kiln or oven. Koyo mesh belt sintering furnace for powder metallurgy. Quite often protective gas has to be used in order to avoid oxidation and corrosion of the metal. This is particularily important because of the large surface area of grouted metal powder, which is very sensitive to oxidation.
Powder metal sintering requires specific gas atmospheres in order to assist de-lubrication and to avoid decarburisation. In addition to supplying the required gases such as nitrogen, hydrogen and carbon monoxide, we offer leading technologies to control the carbon potential and the uniformity of the sintered parts.
Sintering process may be conducted in different atmospheres: air, inert atmosphere, Powder metallurgy,reducing atmosphere (containing Hydrogen or carbon monoxide) or in vacuum. Decrease of the porosity, caused by the sintering process, is determined by the level of the initial porosity of the "green" compact, sintering temperature and time.
sintering times would be preferable; but the correspondingly higher sintering temperatures are less economical because of higher maintenance costs for the sintering furnace. In iron powder metallurgy, common sintering conditions are: 15 - 60 min at 1120 - 1150 ° C. Geometrical structure of the powder particles.
Huichengsheng Industry Manufacture High Temperature Atmosphere Protective Powder Metallurgy Sintering Furnace.
It is highly accepted for Fe-PM parts sintering, MIM, and even refractory and heavy metals and fuel element sintering. Frequently, different furnace approaches are combined: stearate zone = pusher furnace, HT zone = walking beam, rapid cooling = roller furnace, cooling zone = conveyor belt furnace.
Jul 07, 2015 · The heat treatment of powder-metal (PM) parts presents a number of unique challenges, influenced primarily by material and density considerations. Common post-sintering processes include sinter hardening and conventional post-sintering heat-treatment operations.
Soviet Powder Metallurgy and Metal Ceramics September 1977, Volume 16, Issue 9, pp 731–736 | Cite as A sintering furnace with carbon potential control of protective atmosphere
Argon is an inert gas that is used as a sintering atmosphere to prevent gas/solid reactions such as oxidation, nitriding or hydriding. Argon is completely inert, thus, although it can yield sintering atmospheres with low partial pressures of water vapor (dew point), it is extremely difficult and costly to reduce its oxygen partial pressure to below 10 ‒ 6 atm. Inert atmospheres have a
Powder metallurgy – basics & applications Powder metallurgy – science of producing metal powders and making finished /semifinished objects from mixed or alloyed powders with or without the addition of nonmetallic constituents Steps in powder metallurgy:Powder production, Compaction, Sintering, & Secondary operations Powder production:
A relatively newer but vastly used science of sintering metal powders to form various parts is known as Powder-Metallurgy. Microwave Sintering Furnaces. Microwave Sintering furnaces (lab or production scale) operate with Microwave radiation as a source of heating and offer distinct advantages to conventional furnaces.
Maintaining Optimal Atmospheres in Sintering Furnaces . The actual sintering takes place in the high-heat sintering furnace under a hydrogen, or in some applications, a hydrogen-nitrogen atmosphere at temperatures above 2400 °F (1300 °C).
