“…The removal of contaminants and extractives especially on aluminum and wood is due to the mechanical effect of the bombardment by the plasma ions on the surface and to the chemical interaction of the charged particles with the contaminants, as for instance reported by Bónová et al (2015), Polini and Sorentino (2003) for aluminum, or Avramidis et al (2012) for wood. In addition, treatment caused the generation of corrosive structures on steel (Kiyokawa et al 1999;Tang et al 2005;Rodríguez-Villanueva et al 2013;Williams et al 2017), and in general the polar surface states through oxidation (Thomas and Mittal 2013) on all three substrates.…”

Combinations of wood and metal are interesting hybrid composite materials, joining together the low density of wood with the stiffness and strength of metals. Different types of adhesives are used to connect wood and metal elements, but the compatibility between adhesives used and load-bearing materials must be sufficient, which often is challenging. In adhesive bonding technology, surface treatments are a crucial step in the process. In this study, an atmospheric plasma discharge was employed to enhance the adhesion strength of joints between common beech (Fagus sylvatica L.) wood, metals (steel and aluminum alloy), and four different types of adhesives. The optical properties of plasma discharges and its influence on treated substrates' surface morphology depended on the inherent properties of the treated materials. X-ray photoelectron spectroscopy revealed the surface oxidation of all the materials after plasma treatment. Consequently, the surface free energy of all materials increased as well. The positive effect of the plasma treatment on the tensile shear strength of single-lap joints shows a high potential of atmospheric plasma treatment technology for enhancement of adhesives strength of joints combining wooden elements, wood and steel, or wood and aluminum alloys. In addition to that, expensive epoxy and polyurethane adhesives could be replaced by more affordable polyvinyl acetate and melamine-ureaformaldehyde adhesives, and still perform at equal levels if the plasma was applied prior to bonding.

“…The plasma power was 30±120 W and the temperature of the walls of the quartz tube varied from 370 to 400 K with an argon gas flow of 120 ml min ±1 . The mechanism of the phenomenon is not clear, but it has been successfully used for surface modification of polymers, [62] surface treatment of steel, [63] and decomposition of inorganic gases. [64] The last of these applications suggests the technique could be useful for the activation of CVD processes, although it has not been tested for this purpose as yet.…”
