Project details(High performance protection with sol-gel coatings on metals and enamels (SURFPROTECT))
Once synthesized, they were deposited by means of the spin coating method onto two aluminum alloys, 5555 and 3005 used as substrates. The final thickness of the coatings is about 10 µm, for the coating without particles and slightly higher, 12-14 µm approximately, for the coatings with particles. The electrochemical results indicated that, in all cases, the coated samples presented an improvement in the corrosion behavior in comparison with bare alloys in aggressive media of NaCl. The corrosion rate decreased three orders of magnitude for the coatings with particles and lower for those that do not contain particles.
