My research involves advanced characterisation of the effects of thermal exposure on the behaviour of different thermal barrier coating (TBC) systems, currently used in industry. I have experience in the following experimental techniques:
Transmission Electron Microscopy (both TEM and STEM-EDS):- for measuring orientation relationships between coating and thermally grown oxide phases, and finding rutile particles within the Alumina scales.
Wavelength Dispersive X-ray Spectroscopy (EPMA):- for investigation diffusion of both major and minor alloying elements between coating and substrates for different systems, as well as elemental mapping.
Laser ablation mass-spectrometry (LA-ICPMS):- for measuring the distribution of trace elements and their associated phases within coatings.
Glow Discharge Optical Emission Spectroscopy (GD-OES):- Similar to quantitative WDS but over a much larger area of the sample.
X-ray Diffraction (grazing angle):- Observing Coating and Oxide Phase changes over time.
Raman & Photo-Stimulated Luminescence Spectroscopy:- Used as a non-destructive technique for measuring residual oxide stresses, as well as oxide phase identification.
I have also used the following modelling techniques, to better understand some of the mechanical and diffusive behaviour of TBC systems:
DFT (CASTEP):- for calculating Migration energies for diffusive species, defect formation and clustering energies, as well as interface calculations for metal/oxide interfaces.
Finite Element Modelling (Abaqus and Matlab):- Modelling the stress effects of TiO2 inclusions in an alumina matrix within a coating system.
