Towards smart electrolytic plasma technologies: An overview of methodological approaches to process modelling
in Surface and Coatings Technology
Description | The project has achieved breakthroughs in the fundamental understanding of the plasma electrolysis process, which is becoming increasingly important in many indusrial sectors as a means of enhancing the wear and corrosion resistance of lightweight metals such as aluminium and magnesium. This has been acheived through collaborative experimantal and modelling studies, and will result in improvements in process optimisation and in process diagnostics and on-line control. |
Exploitation Route | Producers of plasma electrolytic oxidation processes and end-users of the coatings will benefit. |

Title | High speed synchronised electrical/optical monitoring of the PEO process, using parallel small area samples |
Description | The electrical discharges that take place during PEO are central to understanding and control of the process. It's now known that they have a very short lifetime (~tens or hundreds of microseconds), but tend to occur in "cascades" that persist in the same location for hundreds or thousands of discharges, with a relatively short "incubation period" between each one (that probably corresponds to the period required for the large void left at the site concerned after collapse of the plasma to refill with electrolyte). This understanding has largely arisen from the technique developed in the Gordon Lab. for synchronised monitoring of the electrical current through, and the light emission from, a small area sample (~1 mm diameter) connected in parallel with the main sample. At any given time, there will be no more than one discharge occurring on the small sample, so the associated characteristics can be monitored. |
Type Of Material | Improvements to research infrastructure |
Year Produced | 2015 |
Provided To Others? | Yes |
Impact | This technology has led to detailed study of various characteristics of the PEO process, including the incidence of cathodic discharges, the "soft regime" etc. |
