Plasma coatings as tools for surface treatment are indispensable in many industrial processes today. The development direction of plasma coatings, under normal pressure conditions, has increased significantly in recent years. Our portfolio of coatings covers a wide range, e.g., from purely organic plasma polymer coatings, to carbon-like layers and organosilicon coatings. However, one of the current disadvantages of atmospheric pressure plasma chemical vapour deposition (APPCVD) is the focus on SiOx-based coating systems.
A far wider range of new applications would open up, if it were possible to combine the advantages of APPCVD technology over existing low-pressure applications. This would allow: easier process integration, the elimination of vacuum technology, smaller and more flexible designs (thus lowering clean room costs and allowing locally selective coatings). An expansion of inorganic coating materials would thus be made possible. Initial preliminary testing, using the example of sensory coatings, has shown that although feasible, intensive research work is still required. Only then, it will be possible to supply such sensory coatings, or coating systems, for later economic exploitation.
