Study of nanoparticle adsorption in single discharge of plasma electrolysis

Adsorption of nanoparticles from their suspension into deposited oxide-based layer using plasma electrolysis method was studied for a single discharge. A probe was used for sensing voltage characteristics in front of a pre-treated micro-electrode. The results showed that the nanoparticles were adsorbed exactly from the centered channel of the erupted molten-oxide. Microscopic investigations confirmed the presence of more nanoparticles in the middle of the deposited area.

► Single spark creates a symmetric electrical field in plasma electrolysis.
► Presence of charged nanoparticles and their concentration affect on the quality of discharges.
► Absorption will take effect on the middle channel of single discharge.
► Adsorbed nanoparticles were concentrated in the core of oxide deposited from a single discharge.
