Atmosphere Heat Treatment processes as Carburizing, Nitriding,
Carbo-Nitriding etc 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.
