Role of cathodic current in plasma electrolytic oxidation of Al: A quantitative approach to in-situ evaluation of cathodically induced effects

Advanced surface engineering processes based on polarisation-driven electrochemical reactions can be easily programmed and automated using feedback loops and digital models of the process. Being a distinctive feature of Industry 4.0 manufacturing strategy, such intelligent electrochemical approaches require in-depth understanding of the relations between polarisation conditions, electrical response and surface properties, which are of critical...
