Resumen
BRACHETTI-SIBAJA, Silvia Beatriz et al. Rare Earth Conversion Coatings Grown on AA6061 Aluminum Alloys: Corrosion Studies. J. Mex. Chem. Soc [online]. 2014, vol.58, n.4, pp.393-410. ISSN 1870-249X.
The present work is aimed to investigate the corrosion resistance of rare earth (RE) protective coatings deposited by spontaneous deposition on AA6061 aluminum alloy substrates. Coatings were deposited from water-based Ce(NO3)3 and La(NO3)3 solutions by varying parameters such as rare earth solution concentration, bath temperature and immersion time. The values of the Tafel slopes indicate that the cathodic process is favored by concentration polarization rather than activation polarization.
