“…This, together with hydrogen evolution, contributes towards formation of VGE, whereas deposition of reduced cations changes electrode surface composition. The metal electrode in the cathode treatments can be heated up to 1000 °C, which enables plasma electrolytic carburising and nitrocarburising (PEC/N) and other diffusion-based treatments [45,46]. For the anode EPPs, the electrode area ratio is less critical.…”

Abstract This paper reviews the present understanding of electrolytic plasma processes (EPPs) and approaches to their modelling. Based on the EPP type, characteristics and classification, it presents a generalised phenomenological model as the most appropriate one from the process diagnostics and control point of view. The model describes the system 'power supply -electrolyser -electrode surface' as a system with lumped parameters characterising integral properties of the surface layer and integral parameters of the EPP. The complexity of EPPs does not allow the drawing of a set of differential equations describing the treatment, although a model can be formalised for a particular process as a black box regression. Evaluation of dynamic properties reveals the multiscale nature of electrolytic plasma processes, which can be described by three time constants separated by 2-3 orders of magnitude (minutes, seconds and milliseconds), corresponding to different groups of characteristics in the model. Further developments based on the phenomenological approach and providing deeper insights into EPPs are proposed using frequency response methodology and electromagnetic field modelling. Examples demonstrating the efficiency of the proposed approach are supplied for EPP modelling with static and dynamic neural networks, frequency response evaluations and electromagnetic field calculations.

“…EPHT [3,46] requires film boiling in the VGE. This results in thermal shielding of the working electrode; thus, the power dissipating in the VGE due to Joule heating contributes to a rapid increase of the surface temperature up to ~1000°C in several seconds [61].…”

Abstract-A review of the methods of electrochemical treatment classified as plasma electrolysis is given. Special attention is paid to the physicochemical processes that proceed in electrolytes and the techniques of surface modification and application of protective coatings. The results of investigation of such coatings and surfaces upon electrolytic plasma processing illustrate the efficiency and effectiveness of the method. Being an efficient technique of the surface treatment, which involves both the surface cleaning and plating the coat ing, the plasma electrolytic method is being rapidly developed and adapted for commercial use at present.
