Abstract
SE DESCRIBE EL PROCEDIMIENTO DE FORMACION DE ORIFICIOS Y GRABADOS EN LAS LAMINAS METALICAS, CON RUGOSIDAD DE LOS CONTORNOS INFERIOR A 0,01 MM MEDIANTE UN PROCESO DE DISOLUCION ELECTROQUIMICA. LA DISOLUCION DE ZONAS DE METAL, NO PROTEGIDAS CONTRA EL ATAQUE ELECTROQUIMICO, SE REALIZA MEDIANTE ELECTROLITOS CUYA COMPOSICION ASEGURA SU ACCION DE PULIDO AL METAL; EL REGIMEN DEL PROCESO CONSISTE EN LA APLICACION DE IMPULSOS DE VOLTAJE SUPERPUESTOS A UN VOLTAJE ANODICO CONSTANTE. EN LA CELULA ELECTROLITICA LA HOJA DE METAL SE MONTA EN EL PORTAMUESTRAS SITUADO EN EL FONDO. EL CATODO CONTIENE AGUJEROS PARA PERMITIR EL PASO DE BURBUJAS DE OXIGENO FORMADAS DURANTE EL PROCESO DE ATAQUE ELECTROQUIMICO Y SE SITUA SOBRE EL PORTAMUESTRAS. LAS PAREDES SUJETANDO EL PORTAMUESTRAS Y EL CATODO TIENEN TAMBIEN ORIFICIOS PARA PERMITIR LA SUSTITUCION DEL ELECTROLITO AGOTADO ENTRE LOS ELECTRODOS POR OTRO NUEVO. ESTE PROCEDIMIENTO TIENE UNA APLICACION EN LA MANUFACTURA DE MASCARAS PARA EVAPORACION DE PELICULAS DELGADAS, MEMBRANAS Y REJILLAS METALICAS, FIGURAS GRABADAS EN METAL, ETC. CON RESOLUCION SUPERIOR DE 0,01 MM.THE PROCEDURE FOR THE FORMATION OF HOLES AND ENGRAVINGS IN THE METAL SHEETS IS DESCRIBED, WITH ROUGHNESS OF THE CONTOURS LESS THAN 0.01 MM THROUGH AN ELECTROCHEMICAL DISSOLUTION PROCESS. THE DISSOLUTION OF METAL ZONES, NOT PROTECTED AGAINST ELECTROCHEMICAL ATTACK, IS CARRIED OUT THROUGH ELECTROLYTES WHOSE COMPOSITION ENSURES ITS ACTION OF POLISHING TO METAL; THE REGIME OF THE PROCESS CONSISTS OF THE APPLICATION OF VOLTAGE PULLS OVERLAPPED TO A CONSTANT ANODIC VOLTAGE. IN THE ELECTROLYTIC CELL THE METAL SHEET IS MOUNTED IN THE SAMPLE HOLDER LOCATED IN THE BACKGROUND. THE CATODE CONTAINS HOLES TO ALLOW THE PASSAGE OF OXYGEN BUBBLES FORMED DURING THE ELECTROCHEMICAL ATTACK PROCESS AND IS LOCATED ON THE SAMPLE HOLDER. THE WALLS HOLDING THE SAMPLE HOLDER AND THE CATODE ALSO HAVE HOLES TO ALLOW THE REPLACEMENT OF THE SOLD OUT ELECTROLYTE BETWEEN THE ELECTRODES WITH ANOTHER NEW ONE. THIS PROCEDURE HAS AN APPLICATION IN THE MANUFACTURE OF MASKS FOR EVAPORATION OF THIN FILMS, MEMBRANES AND METALLIC GRIDS, FIGURES ENGRAVED IN METAL, ETC. WITH SUPERIOR RESOLUTION OF 0.01 MM.
