Abstract

EL PROCEDIMIENTO DE DECAPADO EN BAÑO ACIDO QUE CONTIENE UN OXIDANTE SE CARACTERIZA PORQUE PARA AUMENTAR LA CINETICA DE DECAPADO, SE FORMA POR LO MENOS UN COMPUESTO PEROXIGENADO DEL TITANIO O POR LO MENOS DE UN ELEMENTO DE LA FAMILIA DEL TITANIO INCLUIDO EN EL PRODUCTO A DECAPAR, SIENDO IONIZADO EL METAL A UNA VALENCIA SUPERIOR, SE CONTROLA LA FORMACION DEL COMPUESTO PEROXIGENADO POR UNA MEDIDA DEL POTENCIAL REDOX, Y SE LIMITA LA CANTIDAD DE AGENTE OXIDANTE DE FORMA QUE CONSERVE UN POTENCIAL DE OXIDORREDUCCION POR DEBAJO DEL POTENCIAL DE PASIVACION DEL PRODUCTO METALICO.
