Abstract
METODO PARA LA ELIMINACION DE CASCARILLA DE OXIDO DE LA SUPERFICIE DE PIEZAS METALICAS. COMPRENDE LA INMERSION DE LAS PIEZAS DE UN ELECTROLITO CONSTITUIDO POR UNA DISOLUCION ACUOSA DE AL MENOS UNA SAL NEUTRA, TAL COMO CLORURO, SULFATO O NITRATO DE UN METAL ALCALINO O DE AMONIO; AJUSTE DEL PH DEL ELECTROLITO A UN VALOR ENTRE 2,0 Y 3,5; PASO DE UNA CORRIENTE ELECTRICA DE BAJA DENSIDAD, ENTRE 1,55 Y 15,5 A/DM A TRAVES DE LAS PIEZAS EN EL ELECTROLITO, QUE SE MANTIENE A UNA TEMPERATURA COMPRENDIDA ENTRE 65,6JC Y 85JC; RETIRADA DE LAS PIEZAS DEL ELECTROLITO E INRTRODUCCION DE LAS MISMAS EN UNA DISOLUCION Y LAVADO DE LAS MISMAS CON AGUA. TIENE APLICACIONES PARA AL DESCASCARILLADO DE BANDAS O CHAPAS LAMINADAS, BARRAS, ALAMBRES Y PIEZAS TUBULARES.
