The Fraunhofer Institute for Manufacturing Technical Science and Applied Material Research (IFAM) together with the Engineer Bureau of Wolfgang Semrau (IWS) in Bremen, Germany have developed and registered for patent a corrosion protection system based on a pre-treatment with succeeding plasma polymerization.
Tools and building components out of diverse materials and with varying sizes and forms can be equipped with these layers. The coating endures aggressive corrosion controls: they will not become infiltrated and preserve their optical appealing appearance. For example a layer on aluminum endures a corrosion attack with sulfuric acid witat a concentration of 25% at 65° C over 40h long, as well as a salt spraying test over a time period of 1500h.
The primary function as corrosion protection can be combined with further functions: i.e. primer for varnishing or vulcanization, hydrophobe, easy to clean (anti-soiling) surfaces.
The success of the coating
has been founded on the fact that the good properties of a plasma polymerization
coating (high consistency, high chemical stability) were combined with
the optimal material surface pre-treatment of aluminum, so that an optimal
bonding and permanence of the layer is reached. This optimization is in
preparation for steel and copper.
