Knowledge from A - Z


Plasma diffusion, plasma heat treatment

This approach is chosen in industrial plasma surface technology mainly for the incorporation of elements such as C, B, N, S or O. It is also used for various materials within the construction industry.

The special feature is that the intercalated elements can form stable bonds with the elements of the base material. The corrosion protection and the protective effect against wear as well as the high strength values play an important role especially in aircraft and tool construction, but also in machine and vehicle construction.

The treatment of other metals such as aluminum or titanium is also feasible; therefore, the processes are also differentiated according to the type of elements to be incorporated:
Plasma boronizing, -carburizing (the so-called carburizing), plasma carbonitriding, plasma nitriding, plasma oxidizing, etc.

As an example again a parameter window:
Pressure: 10 to 10,000 Pa
Temperature: 300 to 1150 degrees Celsius
Treatment time: minutes to days
Plasma excitation: Direct current and pulsed direct current.
