Atmospheric plasma
Radio Frequency Scanner
Modern trends and challengesNew Material and Coatings development:Composites space, automotive, aviation, constructionsProtective, anticorrosive coatingsFunctional filmsFlexible printed circuit boardsChallenge: low adhesion level
Chemical/Electro-chemical methods toxic, product utilization problem, high specialization, inertness, multistep processingUV-treatment low intensity, ozone generationPlasma methodsLow pressure high cost, high resultIon gunPlasma treatmentAtmospheric methods cheap, lower intensityCorona/Dielectric Barrier Discharge low stability, large areas, high power consumptionRF Jet treatment high stability, small areas
Existing Technologies
Plasma surface treatment leads to:Dirt, dust, oil removalSterilization (due to UV-generation)Relief complexity increaseFunctional groups formation (OH-, COC-, CH3- etc.)Benefits: Unselective process can be applied to metals, plastics, glass, othersControlled treatment intensityEco-friendly technologyBetter precision (against chemical methods)
Less defect rate, the protective coating is much more stable, it is possible to use unique combinations of materials, with the exception of primer, etc.Trend: plasma activation usage. Why?
What are the methods nowadays?Benefits and limitationsLarge-scaleHigh power consumptionLow stabilityHigh ozone generationSpot-scaleLow power consumptionHigh stabilityLow ozone generation
