The reduction of metal surfaces with atmospheric plasma processes is suitable for a variety of metals and alloys.

Plastics are usually characterized by inert surfaces with surface energies between 20 and 40 mN/m. In order to wet a surface, however, the surface energy of the polymer must exceed the one of the paint or the adhesive. This condition can be achieved through a plasma treatment of the surface and is called “activation“ in plasma technology.

Cold atmospheric pressure plasmas are now being widely used for many types of surface disinfection and sterilization. Despite the wide area of applications and high demand for new effective treatments, the understanding of interactions of plasmas with living cells and tissue remains rather limited.

The high temperatures which are reached in most plasma applications make many users wonder about process safety, especially when highly sensitive materials are treated. This article addresses open questions concerning temperature and heat conduction during plasma applications and cites critical examples which substantiate the suitability of plasma for temperature-critical processes.
