Electrolysis of aqueous solutions at high voltage which is accompanied by plasma discharge phenomena at the solid/ electrolyte interface is a dynamic field of surface engineering; plasma-assisted electrolysis processes underlie a group of electrochemical techniques for surface treatment of technological components to improve performance in operating conditions, increase life time, and reduce production costs. The purpose of controlled surface modification is to reduce corrosion, reduce energy losses through friction, reduce wear, achieve thermal or electrical insulation. The sample to be treated is placed as a working electrode, either anode or cathode, in an electrolytic bath of suitable composition, the treatment techniques being classified in anodic and cathodic techniques, depending on the polarity applied to the treated sample.
ELSSA LABORATORY SRL conducts scientific research activities for the development of applications of surface engineering techniques based on the use of electrolysis plasma.

Research directions:
- Development of ceramic thin films by plasma electrolysis oxidation on steels, zirconium alloys, titanium and magnesium alloys;
- Carburizing, nitro-carburizing, boro-nitro-carburizing on steels and titanium alloys by saturation in electrolytic plasma.
