Abstract

UN METODO DE PRODUCIR UNA CUCHILLA DE TURBINA DE GAS TENIENDO UNA PUNTA ABRASIVA, COMPRENDE LA PRODUCCION DE UNA CAPA ENLAZADORA 81 EN LA PUNTA DEL CUERPO DE LA CUCHILLA (8) POR ELECTRODEPOSICION, LA CAPA ENLAZADORA CONTIENE MCRAIY DONDE M ES UNO O MAS DE HIERRO, NIQUEL Y COBALTO, ANCLADOS A LAS PARTICULAS GRUESAS DE LA CAPA ENLAZADORA (83) DE UN MATERIAL ABRASIVO POR ELECTRODEPOSICION COMPUESTA DE LAS PARTICULAS Y UNA CAPA DE ANCLAJE (82) DE UN BAÑO DE DISOLUCION CULTIVADA SOBRE PLACA TENIENDO EN ELLA SUSPENDIDAS LAS PARTICULAS ABRASIVAS, Y DESPUES CULTIVANDO SOBRE UNA PLACA UN RELLENO (84) ALREDEDOR DE LAS PARTICULAS ABRASIVAS. LA CAPA DE ANCLAJE (82) PUEDE SER DE COBALTO O NIQUEL O MCRAIY COMO SE DEFINE ARRIBA Y TIENE PREFERIBLEMENTE UN GROSOR MENOR DE 3 (MU)M. EL MATERIAL DE RELLENO PUEDE TAMBIEN SER MCRAIY COMO SE DEFINE ARRIBA. LA DEPOSICION DEL RELLENO (84) PUEDE PREFERIBLEMENTE SER ACOMPAÑADA POR LA VIBRACION DE LA CUCHILLA EN UNA DIRECCION QUE ES SUSTANCIALMENTE VERTICAL Y A LO LARGO DEL EJE DE LA CUCHILLA.
