• Chromate inhibited primer
• X-ray tomography
• Positron annihilation spectroscopy (PALS)

Model paint materials were generated by adding a range of inorganic materials into an epoxy. The inorganic materials included inhibitors (Zn-3(PO4)(2) and StCrO(4)) and a filler (rutile TiO2).The SrCrO4 system was characterized using SEM, TEM, PALS and Raman spectroscopy and found to have an even distribution of inhibitor in the polymer matrix. X-ray tomography was performed on the mixed SrCrO4/TiO2 and Zn-3(PO4)(2)/TiO2 systems. A new technique called data constrained modelling was combined with the tomographic technique to produce a 3D distribution of the inorganic phases within the polymer matrix.
