- Rare Earth Conversion Coatings Grown on AA6061 Aluminum Alloys. Corrosion Studies Silvia Beatriz Brachetti-Sibaja Miguel Antonio Domínguez-Crespo Aidé Minerva Torres-Huerta Edgar Onofre-Bustamante Wencel De La Cruz-Hernández Multidisciplinaria (Ciencias Naturales y Exactas) Cerium oxide Aluminum alloy Lanthanum oxide Rare earth elements Corrosion evaluation The present work is aimed to investigate the corrosion resistance of rare earth (RE) protective coatings deposited by spon - taneous deposition on AA6061 aluminum alloy substrates. Coatings were deposited from water-based Ce(NO 3 ) 3 and La(NO 3 ) 3 solutions by varying parameters such as rare earth solution concentration, bath temperature and immersion time. The values of the Tafel slopes indi - cate that the cathodic process is favored by concentration polarization rather than activation polarization. 2014 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47535733005 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.4 Vol.58
