Environmentally Friendly Surface Preparation and Enhanced Adhesion Through Advanced Plasma Technologies
Atmospheric plasma processes offer environmentally sustainable surface treatment solutions by significantly reducing or eliminating harmful solvent emissions in industrial production, thus enhancing workplace safety. Beyond these ecological advantages, plasma technology provides superior performance compared to traditional methods, enabling precise process control and seamless inline integration. This work highlights the benefits of atmospheric plasma treatment for enhanced adhesion in bonding and painting applications. Furthermore, to address demanding needs in harsh environments, Plasma-Enhanced Chemical Vapor Deposition (PECVD) is explored for depositing ultra-thin functional coatings. By carefully controlling plasma parameters, these tunable films impart exceptional properties such as corrosion protection and enhanced chemical reactivity, crucial for robust adhesion. Our findings demonstrate the transformative potential of PECVD in improve corrosion protection and achieving durable bonds on stainless steel and aluminum alloys, yielding a remarkable increase in bond strength (from 3 MPa to 12 MPa for steel and a tenfold improvement for aluminum) even after aging. These results underscore the dual impact of plasma technologies: driving sustainability while delivering unparalleled performance in critical applications.
