Surface oxide formation during corona discharge treatment of AA 1050 aluminium surfaces

Microdischarges properties in sDBD: the role of the exposed electrode oxidation

“…The modification of electrodes in air is associated, on the one hand, with the redeposition of the oxide onto the surface of the electrode, and on the other, with its erosion. The latter is the result of the accumulation of many destructions caused by single MD [32,33]. The mechanisms of the oxide layer formation depend on the resistance of the electrode material to oxidation.…”

Polyurethane paint adhesion improvement on aluminium alloy treated by plasma jet and dielectric barrier discharge

“…[20] There are some investigations about the use of different types of plasma for aluminium alloys surface treatment. The authors [21,22] reported the effects of the corona discharge on an Al alloy. The eletrochemical tests showed a significant reduction in anodic and cathodic reactivities with the formation of a thicker Al oxide film.…”

Generation of Porous Alumina Layers in a Polydimethylsiloxane/Hydrogen Peroxide Medium on Aluminum Substrate in Corona Discharges

“…Recent research studies in the field of anodization methods of aluminum were directed toward alternative methods for the generation of alumina layers, namely, corona discharge treatments [2]. Running of these kinds of discharges in air at atmospheric pressure has the unique advantage of simultaneous production of charged (negative or positive ions) and neutral (e.g., O 3 ) species of oxygen known for their reactive character in the interaction with materials.…”

“…Over the time, alumina layers have been intensely studied due to their widespread application in corrosion protection for aerospace, automotive, architectural, or packaging [2]. Their nontoxic and biocompatible properties make them also attractive for biotechnological applications [3].…”
