Corrosion protection characteristics of ceramics, porphyrins and hybrid ceramics/porphyrins, deposited as single and sandwich layers, by pulsed laser deposition (PLD)

The performed tests revealed that the best results were obtained for sandwich structures using Zn3Ta2O8 as first layer and 5-(4-pyridyl)-10,15,20-tris(phenoxy-phenyl) porphyrin (PyTFen) as the second layer, i.e. 77% inhibition efficiency.
