Atmosphere Heat Treatment processes such as Hardening 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.
