Atmosphere Heat Treatment processes such as gas nitriding are
basically used for the manufacturing of different kind of components
and parts which are needed in the automobile-, aircraft- and
machinery-industry in order to optimize the specific characteristics of
the material. Correct gas-atmospheres are necessary to transfer carbon
and/or nitrogen in the components, in order to improve hardness and
lifetime.
Protective gas-atmospheres help to avoid oxidations
during hardening processes. Some main parameters which influence the
processes and can create large financial losses in case of failure are
listed:
- quality of used material
- selection of material according to applications
- pre-treatment of components and parts
- quality of atmosphere and used gases
- temperature profiles
- quenching criteria
- process control systems
- processes
All
heat treatment processes are empirical processes. Therefore, the best
solutions can be only found with the help of Experts with outstanding
experiences.
