Abstract

PROCEDIMIENTO DE FABRICACION DE SONDAS PARA EL TRATAMIENTO DE ALUMINIO FUNDIDO Y SIMILARES. PARA LA FABRICACION DE LA SONDA (1) SE PARTE DE UNA BARRA DE TITANIO FORJADO Y SE REALIZA UN CUERPO (3) QUE TIENE DOS EXTREMOS OPUESTOS (5, 7), CADA UNO TERMINADO EN UNA SUPERFICIE PLANA (9); LA SONDA TIENE UNA PUNTA OPERATIVA EN UN EXTREMO (5) QUE DEBE SER RELATIVAMENTE CORTA Y PUEDE INCLUIR UNA SUPERFICIE REFLECTANTE (23), DEFINIENDOSE UNA CAVIDAD (27) QUE QUEDARA LLENA DE METAL FUNDIDO. EN EL CUERPO (3) SE PREVEEN MEDIOS DE REFRIGERACION COMO UNA CAMISA (31) DE CAPACIDAD SUFICIENTE PARA REFRIGERAR LA SONDA CUANDO LA PUNTA OPERATIVA, SUMERGIDA EN UNA COLADA DE ALUMINIO, ALCANZA SU EQUILIBRIO TERMICO ENTRE 675<025>C Y 825<025>C. LA REALIZACION DE LA PUNTA OPERATIVA SE LOGRA LIMPIANDO CON SOLUCION ACIDA SU SUPERFICIE PARA ELIMINAR LOS OXIDOS DE TITANIO; A CONTINUACION SE MANTIENE EN UNA ATMOSFERA DE VACIO A PRESION ENTRE 50 Y 300 MICRAS ENTRE 15 Y 60 MINUTOS,, TERMINANDO SU LIMPIEZA CON UN BOMBARDEODE GAS IONIZADO A PARTIR DE UN DESCARGA DE CATODO FRIO; SEGUIDAMENTE SE DISMINUYE LA PRESION DE LA ATMOSFERA DE VACIO A UN VALOR ENTRE 0,05 Y 0,5 MICRAS Y SE VOLATILIZ EN LA MISMA ALUMINIO DURANTE UN TIEMPO ENTRE 15 Y 30 SEGUNDOS PARA QUE SE DEPOSITE SOBRE LA SUPERFICIE DE LA PUNTA. LA PUNTA ASI REALIZADA SE SELLA SUMERGIENDOLA EN UNA COLADA DE ALUMINIO. EN LA SONDA SE ACOPLA UN DISPOSITIVO TRANSDUCTOR PIEZOELECTRICO (13) QUE EMITE Y RECIBE LAS ONDAS ULTRASONICAS HACIA Y DESDE LA COLADA DE ALUMINIO, SIENDO LA SONDA EL PORTADOR DE LAS MISMAS.
