Abstract
Procedimiento para mejorar la resistencia a la corrosión de los radiadores de cobre y de aleaciones de cobre, caracterizado por el hecho de que se someten los radiadores, después del ensamble y soldadura de los componentes, a las siguientes operaciones: lavado en frío, desgrasado, enjuague con agua fría, enjuague con agua desmineralizada, fosfatación formadora de película en la superficie, con soluciones en agua desmineralizada, de ácido fosfórico o sus derivados, ácido crómico o sus sales, agentes reductores de cromo hexavalente, a cromo trivalente y resina polimérica. Eliminación del exceso de dicha solución de fosfatación formadora de película; secado, lijado en tinta, aplicación de barniz en polvo y horneo de barniz.
