Abstract

Se describe un proceso libre de cromo, para la provision de una superficie metálica con las propiedades de resistencia contra la corrosion, hidrofilicidad, bajo olor y biorresistencia. El proceso incluye inicialmente el tratamiento de metal con una solucion de fluoruro, circonio y un ácido protico. Posteriormente, el metal se trata con una solucion de silicato soluble en agua a un Ph alcalino,. Se utilizan opcionalmente enjuagues después de cada etapa, y se prefiere una etapa de secado en horno como el paso final en el proceso.
