Abstract

EN LA FABRICACION DE MATERIALES CON RADIACION LASER (11,12) SE FORMA UNA PLASMA (14) EN DIRECCIONES ALTAS DE RAYOS. ESTA IMPIDE UNA TRANSMISION DE ENERGIA SOBRE LA PIEZA DEL TRABAJO (10) POR SU ABSORCION DE LOS RAYOS LASER. PARA NO DAÑAR LOS ELECTRODOS RESPONSABLES PRINCIPALMENTE PARA LA ABSORCION, SE SOLAPA HELIO, QUE TRANSPORTA LA RECOMBINACION DE ELECTRODOS E IONES, SOBRE LA POSICION DE ELABORACION (13). ESTE INVENTO UTILIZA EN VEZ DE HELIO CARO, EL GAS, DISPONIBLE FACILMENTE CF4 Y/O SF6, JUNTO CON UN GAS DE INFLAMACION / INERTE, QUE ESTA MEZCLADO CON MENOS DE 25%, SE LOS SOPLA (16) POR UN INYECTOR (15) A LA POSICION DE LA ELABORACION (13), DONDE ESTOS FORMAN FLUORRADICALES ELECTRONEGATIVOS FUERTEMENTE BAJO LA INFLUENCIA DE LA TEMPERATURA ALTA, QUE EXTRAE DE LA PLASMA (14) LOS ELECTRODOS. SOBRE LA COMPOSICION DE LA MEZCLA ES DIRIGIBLE ESTE PROCESO. EL ANTEDICHO PROCEDIMIENTO ES APROPIADO ESPECIALMENTE PARA LA ELABORACION DE METAL, ESPECIALMENTE ALEACIONES DE ALUMINIO.
