Abstract

MEDIO PARA DECAPAR LA SUPERFICIE DE ACERO INOXIDABLE Y ACERO AL CROMO QUE CONTIENE ACIDO SULFURICO ACIDO FOSFONICO O SUS MEZCLAS E IONES (FE (III), ADICIONALMENTE EL MEDIO CONTIENE ACIDO FLUOROBORICO. CON ESTE MEDIO SE CONSIGUE EL DECAPAR SUPERFICIES DE ACERO INOXIDABLES Y DE ACERO AL CROMO, YA QUE SE ELIMINAN CAPAS DE OXIDO NO DESEADO, IMPUREZAS Y COLORACIONES DE REVENIDO. CON EL MEDIO SE PUEDE ABANDONAR EL UTILIZAR ACIDO FLUORHIDRICO POR EJEMPLO ACIDO FLUORHIDRICO JUNTO A ACIDO NITRICO.
