Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO PARA MEJORAR LA SALUD SUPERFICIAL DE PRODUCTOS DE ALEACION DE AL QUE CONTIENE LI. ESTE PROCEDIMIENTO CONSISTE EN UTILIZAR EN EL CALENTAMIENTO, A UNA TEMPERATURA SUPERIOR A 300 GRADOS C, UNA ATMOSFERA QUE CONTIENE (EN VOL. %) CO2: 5 A 98%; 2<= AIRE (SECO) <= 95; RESTO=AGUA. ESTE PROCEDIMIENTO EVITO LA APARICION DE PICADURAS SUPERFICIALES Y REDUCE LA PROFUNDIDAD DE LA ZONA SUPERFICIAL EMPOBRECIDA EN LI.
