Ultrathin functional layers

For the production of ultra thin layers, which play an important role as functional coatings in many technical components, in particular chemical and physical deposition techniques in the gaseous phase are employed. The differences between the multiciplity of procedures lie mainly in the methods for the supply of the deposition material, reachind from CVD to high-energy particle beam procedures. Also by ion implantation na-nostructured surfaces can be obtained. All methods are already used in the range of microtechnologies. For application in nanotechnology, a highly precise control of all process parameters is important. Also from liquids, extremely thin layers with controlled molecular architecture (e.g.

Langmuir Blodgett films or self assembling monolayers) can be produced. With nanostructured layers varied surfaces can be obtained with super hard, corrosion resistant or friction-reducing properties with dependence on the used coating materials and processes. In the following possible space applications of such functional layers are discussed.
