Viele thermoplastische Kunststoffe lassen sich sehr schlecht verkleben. Eine Aktivierung mit Atmosphärendruck-Plasma steigert in nur einem Prozessschritt die Haftkraft der Verbindung erheblich. Die Suche nach der Ursache birgt einige Überraschungen.

Using a risk assessment methodology applied on empirical data and failure scenarios, we have been able to prove that our plasma systems reach a high performance level and safety. Using the modern approach of redundant safety circuits critical hazard can be avoided efficiently.

A large number of metals and alloys can excellently be cleaned, oxidized or efficiently reduced using atmospheric plasma processes. The technique is suitable for single sensitive items such as cultural assets, coins, jewelry etc., or it can equally be operated in a continuous process. Role plating was used as an example to show the lasting effect of an atmospheric hydrogenous plasma jet.

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.

Through a simple measurement of the surface energy, the activation capacity of a surface treatment may be evaluated and quantified. This allows for a quantitative comparison of the performance and efficiency of various methods of surface treatment using a physically defined quantity.
