The plasma processes e.g. plasma nitriding/nitrocarburizing are also thermo-chemical processes with the big advantage to exclude oxygen and to shorten the process time essentially.

Also with these processes a lot of mistakes can occur in case the right  parameters are not combined.

The main scope of problems is listed below:

• quality of used material
• selection of material according to applications
• pre-treatment of components and parts
• quality of atmosphere and used gases
• temperature-profiles
• pressure
• tension
• power-density
• quenching-criterias
• process-control-system
• processes

All heat treatment processes are empirical processes. Therefore the best solutions can be found with the help of experts with outstanding experiences.
