Abstract
Tratamiento de conversión química para el magnesio y sus aleaciones. La presente invención se refiere a un procedimiento de tratamiento de conversión química superficial de magnesio o sus aleaciones que comprende someter una pieza de magnesio o aleación del mismo a las siguientes operaciones: a) desengrasado, b) enjuague con agua, c) decapado alcalino, d) enjuague con agua, e) decapado ácido, f) enjuague con agua, g) tratamiento de conversión química mediante la aplicación sobre la pieza de un baño que consiste en una disolución acuosa de permanganato de un metal alcalino y fosfato de un metal alcalino, h) enjuague con agua, i) secado y j) almacenamiento. Se refiere también al baño de conversión química que consiste en una disolución acuosa que tiene como componentes principales permanganato de un metal alcalino y fosfato de metal alcalino, con el pH entre 2 y 5 ajustado con un ácido mineral y que se aplica a una temperatura de 20 a 40ºC; y a los productos de magnesio o sus aleaciones que llevan un revestimiento producido por dicho baño de conversión química.
