| Description | Methodology to analyse PEO plasmas. |
| Exploitation Route | Changes in electrolyte composition will lead to changes in plasma temperature, density (as detected) which in turn results in different coatings. |
| Sectors | Aerospace, Defence and Marine,Energy,Manufacturing, including Industrial Biotechology,Transport |
| Description | The findings advance our understanding of the PEO process for the production of coatings on different alloys. It is being exploited by Keronite Ltd to produce high performance coatings for aerospace, oil/gas exploration and elite sports equipment and has inspired academic research activities in Europe, America and China. |

| Title | Fitting procedure for estimation of temporal variations in rotational and vibrational temperatures of OH radical during PEO process |
| Description | Rotational temperature (if OH spectrum is measured with 308nm, 310nm, 312nm central wavelength positions) and vibrational temperature (if OH spectrum is measured with 312nm central wavelength position). The background intensity automatically taken off in the program, the experimental offset error is automatically calculated as well. The inputs 'centre_w' and 'g_lines' must match the centre wavelength and grating line-density that were used for the spectroscopic measurements. The spectral inputs 'lambda' and 'spectra' will normally be loaded from a suitable data file before calling the function. The inputs 'gwidth' and 'Lwidth' are the Gaussian and Lorentian widths of 'instrumental function' to be used for fitting the OH lines. These are the overall values and include both the real spectral broadening and the effects of the instrument function. |

| Results and Impact | Presentation at the meeting with EADS Innovation Work UK, Filton, 9 December 2011. Research team at EADS UK is currently looking at the diagnostics tools for lightning protection experiments. My talk provided examples together with some practical advice of emission spectroscopy as a diagnostics tool. |

| Results and Impact | Oral presentation at Euromat 2011, 12-15 September 2011, Montpellier, France. Symposium: C42 Advances in surface treatments of light alloys. My talk provided examples together with some practical advice of emission spectroscopy as a diagnostics tool for PEO. Examples of measured molecular rotational and vibrational temperatures were given. They were compared with electron excitation and translational temperatures. The plasma in vapour bubbles is close to thermal equilibrium with reasonably low degree of ionisation. |

Large event (~2000 participants) organised by The Federation of European Materials Societies After my talk, several questions have been exposed to the audience. 1) If there are different spectroscopic signature of OH and Al emission, would it be possible to separate one from another by gating of the signal? 2) How to estimate gas pressure in discharge bubbles? 3) Any possibility of time resolved spectroscopic measurements? |
