Abstract

Procedimiento para la protección frente a la corrosión externa en intercambiadores de calor a base de cobre. El procedimiento comprende el recubrimiento y difusión térmica de una aleación a base de Sn sobre un núcleo a base de Cu, con lo que se forma un material composite constituido por un núcleo a base de Cu, una superficie externa constituida por una aleación a base de Sn y una capa intermedia constituida por aleaciones Cu-Sn de composiciones variables. Dicho material composite formado es adecuado para la fabricación de aletas para intercambiadores de calor, particularmente radiadores para automóviles, cuyos panales pueden soldarse en un horno con atmósfera oxidante o no oxidante.
