Corrosion Protection Of 304 Stainless Steel With Melting Gels Coatings, Mario Aparicio, Andrei Jitianu, Gabriela Rodriguez, Ahmad Dengah, Kutaiba Marzoki, Jadra Mosa, Lisa C. Klein

Publications and Research

Methyl-substituted melting gels were used to coat AISI 304 stainless steel substrates. Crack-free coatings up to 1 mm in thickness were obtained. SEM micrographs of cross-sections con fi rm good adhesion to the surface. Samples were subjected to structural characterization using FT-IR, and Raman spectroscopy. Mechanical properties were investigated by micro-scratch tests. Electrochemical analyses (anodic polarization and electrochemical impedance spectroscopy) were performed in 3.5% NaCl solutions. Electrochemical tests show excellent performance of the coatings against corrosion with no sign of degradation after several months of immersion.
