FOCUS ON SURFACE TREATMENT

manufacturing electronic components. Plasma systems and reduction were also demonstrated live here.
The workshop on“ Cleaning Reimagined: From Openair-Plasma to HydroPlasma” showcased a world-first from Plasmatreat. This innovation involved adding distilled water to a plasma jet, which enhances the plasma treatment’ s effectiveness. Using small metal plates contaminated with fingerprints, the company demonstrated that HydroPlasma can remove even stubborn contaminants( such as oils, salts and fat), without the use of wet chemistry and in a way that can be verified using measurement instruments.
As the title of another workshop in the main building“ Innovative Technology and Forward- Looking Coatings,” suggested, this workshop focused on PlasmaPlus PT-Bond technology. This technology enables the application of ultra-thin coatings to materials by injecting gaseous precursors into plasma jets via special plasma nozzles.
“ The plasma, enriched in this way, then hits surfaces that were previously treated with Openair-Plasma technology, coating them with ultra-thin, transparent plasma polymer layers. These layers can include bonding agents for structural bonding, as well as barrier and insulation layers for corrosion protection. The workshop featured a thermoforming application in which sheet metal was coated with an ultra-thin protective layer, instead of a film, to prevent scratching. This is one example of many applications in which plasma technology

can replace consumables, positively impacting operating costs and process sustainability,” commented Plasmatreat.
Assembly bonding and corrosion protection
As was made clear in the technical presentations, assembly bonding is becoming a popular joining technology in a growing number of industrial sectors. Lukas Buske’ s example of the complete bonding of all car body elements demonstrated how far development has progressed in this area. Further examples were discussed in the workshop,“ Plasma Meets Polymer: Efficient
Activation for Maximum Adhesion” in the Application Technology Laboratory.
Corrosion protection was also the subject of a separate workshop,“ AntiCorr as a protective shield for surfaces.” This workshop took place in Plasmatreat’ s contract service area. It demonstrated the process of cleaning and coating a customer’ s battery housing made of aluminium die-cast and continuous cast aluminium with AntiCorr. For this purpose, a robot equipped with an Openair-Plasma nozzle and a PlasmaPlus nozzle was used.
“ This process effectively protected the battery tray against crevice corrosion while using minimal precursors,” confirmed Plasmatreat.
A total of eight workshops, held over the day, covered the current state and future of plasma technology in various application areas. n
