Summary

Seven luxemburguish industries have worked during four years and half with CRP-GL, CRP-HT and the University of Luxembourg to evaluate the potentialities of different plasma processes to achieve new surface functionalities on different materials as metal sheets and metallic, organic products. New collaborations with European academic universities and research centers were also established to transfer a scientific and experimental know-how towards the CRP. This last period was dedicated to finalize the more promising scientist results and industrial developments. PVD technologies with ionized plasma assisted magnetron sputtering processes are appropriate techniques to elaborate protective coatings in very corrosive media and in extreme conditions (high temperature and high mechanical stresses).

Two nickel based alloys have shown a very high corrosion protection for stainless steel products in both chlorinated and fluorinated media. The deposition of TiAlSiN coating with a nanocomposite microstructure is the most promising solution to improve the wear resistance of wire. The evaluation has been concluded on wire coated into an air-to-air continuous PVD process and used with a laboratory silicone cutting tool. Optimized parameters for an atmospheric plasma treatment has been determined for two objectives: the first is the promotion of a strong chemical adhesion between cooper foils and their dielectric support and the second is, the plasma surface preparation of vulcanized rubber to improve its adhesion with a silicone adhesive/silicone sheet.

For both applications, adhesion measurements by peel-test techniques, higher than 1N/mm have been achieved. This performance has also been correlated with chemical surface analyses to interpret the level of adhesion performed. High diversity of organic and inorganic films can be deposited on aluminium foils. By tuning plasma parameters and by depositing multilayers, it is possible to obtain very high efficient barrier thin films. It is also possible to add, in a single in-line process, chemical functions in order to favour further adhesion of a thick organic topcoat (lacquer) The performances of solutions were correlated to existing products taking into account their manufacturing cost.

Reduction of raw material consumption and treatment time is carried out in case of organosilicon plasma polymerized coatings for corrosion protection of galvanized steel. Nevertheless, at this stage, such an improvement does not allow implementation of this atmospheric plasma process in industry since the cost and environmental impact are currently not low enough. Active corrosion protection is provided when cerium containing nanoparticles are incorporated into the organosilicon layer. Cerium oxide particles incorporation gives better dispersion and active properties as compared to AlCeO3 particles.
