Abstract

Un procedimiento para mejorar la resistencia a la corrosión de objetos de hierro, acero y aleaciones de hierro, mediante la aplicación de una capa de fosfatos, caracterizado porque los objetos oxidados o corroídos, son tratados, sin decapado previo y a una temperatura de 50-100ºC, con una única solución de decapado y fosfatado.
