Abstract
Una composicion de recubrimiento inhibidora de corrosion, de no cromato, para superficies de metal incluye por lo menos un inhibidor seleccionado del grupo que consiste de fosfatos, fosfosilicatos, silicatos, y mezclas de los mismos, por lo menos un inhibidor seleccionado del grupo que consiste de titanatos, sales de cinc, y mezclas de los mismos, y un portador para estos inhibidores, siendo capaz el portador de colocar los inhibidores en proximidad con la superficie de metal. En una modalidad preferida, la composicion de recubrimientos incluye además un borato tal como ácido borico y un succinato. Un fosfato preferido incluye fosfato diácido de calcio, y oxido de titanio sodico es un titanato preferido. La sal de cinc puede incluir fosfato de cinc o cianamida de cinc.
