Due to the structure of the metals which is appropriate for creating compounds during heat treatment procedure as a result of high temperatures, nitrogen gas is used to prevent harmful effects such as oxidation, corrosion, rust etc.
Tempering
The stretching of materials is preventing during tempering procedures and their mechanical properties are improved. During the procedure, the material which reaches high temperatures should be separated from oxygen, humidity and other air elements. By preventing oxidation and formation of rust or corrosion layer and in order to create high quality surfaces, a nitrogen atmosphere is created with Ideal Makina Nitrogen Generator inside the stove. Normalization tempering uses this procedure continuously.
Soldering
Nitrogen atmosphere is required to establish high quality levels on the combination surfaces of the soldering material which melts at high temperatures inside soldering stoves.
Carburization and Cementation
Within thermochemical processes, for example during cementation, steel material’s surface is infused with carbon at a temperature between 850-950oC and it is hardened as a result. During this procedure, water vapour, oxygen and CO2 gas in the environment is removed with the help of the nitrogen gas to prevent decarburization on the surface.
Hardening
You can also use Ideal Makina Nitrogen Generators for hardening procedures to create a nitrogen atmosphere that would prevent oxidation and decarburization as in the case of carburization.
Galvanization
Galvanization procedure uses nitrogen to scrape the excessive zinc on the surfaces that are galvanized. Nitrogen gas generated with Ideal Makina Nitrogen Generators can be given to these systems via manual or automatic systems.
Degasification
Oxygen molecules are present inside the aluminum found as melted mostly at aluminum melting mines. The structure of aluminum allows creating compounds with oxygen at high temperatures. Here nitrogen atmosphere is created inside the stove to prevent oxidation. Moreover, air bubbles are prevented from being created inside the solid aluminum thanks to the nitrogen atmosphere.
