| Popis: | In this paper the corrosion protection of silicon-organic coatings applied by an atmospheric pressure plasma jet system was studied on copper (Cu) and aluminium (Al). The influence of a plasma pre-treatment on the defect density and the adhesion of the subsequently deposited plasmapolymer coating are presented. The quality of the coating was studied via visualization of defects by means of silver precipitation. Use of a reductive gas mixture for the plasma pre-treatment led to a significant reduction of the defect density. Additionally, the implementation of chromate-free corrosion inhibitors in the plasmapolymer layer enables an active corrosion protection of Al surfaces. |
