To control the properties during sintering, PM parts fabricators have to control the temperature and atmosphere in sintering furnaces. A common furnace atmosphere is nitrogen (N2) and 10% hydrogen (H 2), although a mixture of other gases can be added.1 For example, adding a small amount of methane (CH4) can help avoid decarburization.
(1) the temperature in the nitriding furnace is not uniform due to unbalanced heating on and off the nitriding furnace or unobstructed air flow. (2) partial blockage of ammonia gas into the pipeline, affecting nitrogen atmosphere in the furnace; The ammonia gas circulation in the furnace is bad.
The C.I. Hayes "CVCQ-LAM" Vacuum Sintering Furnace uniquely combines atmosphere delubrication and vacuum sintering. An in-line atmosphere delube/preheat section and integral vacuum sintering chamber allow for processing of powder metal (P/M) compacts at conventional or high temperatures.
Nabertherm does not only offer the widest range of standard furnaces. Professional engineering in combination with in house manufacturing provide for individual project planning and construction of tailor-made thermal process systems with material handling and charging systems. Complete thermal processes are realized by customized system solutions.
2018111Argon and nitrogen are the most utilized gases for cooling during thermal processing in vacuum furnaces. Nitrogen (AW = 14.0067) is approximately 2.9 times lighter than argon (AW = 39.948). Nitrogen has a faster cool rate (approximately four times faster than argon) and is much cheaper than argon (approximately eight times cheaper).
The rates of chemical processes and their variation with conditions have beenstudied for many years, usually for the purpose of determining reaction mechanisms.Thus, the subject of chemical kinetics is a very extensive and importantpart of chemistry as a whole, and has acquired an enormous literature.

Synthesis and Sintering of AlN using Enriched Nitrogen Tadashi MARUYAMA+ and Makoto ISHIKAWA Power Reactor and Nuclear Fuel Development Corporation* (Received January 8, 1996) A high purity A1 powder was directly reacted with isotopically enriched 15N, gas at 1,200"C in a vacuum furnace to synthesize Al15N.
200979This object is achieved by a method for sintering in a controlled furnace atmosphere, wherein said furnace atmosphere is a hydrogen-free atmosphere comprising nitrogen and carbon monoxide. According to the invention a furnace atmosphere is used which is essentially free of hydrogen and which comprises nitrogen and carbon monoxide.
Once the debinding step is completed, the components are laid into a sintering furnace where they are heated until they reach a temperature which is lower than the melting temperature of the metal powder's main constituent. During this process, the powder mass bonds and this allows to achieve a near full density component.
There a total of five (5) zones with two (2) in the pre-heat and three (3) in the high heat. The high heat section is atmopsphere tight. This furnace is currently designed to be used with a ceramic belt which is not included with this furnace. Furnace can be modified to accept a wire mesh belt at an additional cost. Condition: Very Good
