Abstract

UNA VALVULA DE ESCAPE PARA UN MOTOR DE COMBUSTION INTERNA COMPRENDE UN VASTAGO MOVIL CON UN DISCO DE VALVULA DE ALEACION A BASE DE NIQUEL, QUE CONSTITUYE TAMBIEN UNA SUPERFICIE ANULAR DE ASIENTO SITUADA EN LA SUPERFICIE SUPERIOR DEL DISCO DE LA VALVULA. EL AREA DE ASIENTO SE PONE EN CONTACTO CON UN AREA CORRESPONDIENTE DE ASIENTO DE UN MIEMBRO FIJO DE LA VALVULA, EN LA POSICION CERRADA DE LA MISMA. EN EL MOMENTO DE LA FABRICACION, EL AREA DE ASIENTO DEL DISCO DE LA VALVULA SUFRE UN PROCESO DE DEFORMACION TERMOMECANICA A UNA TEMPERATURA INFERIOR A LA TEMPERATURA DE RECRISTALIZACION DE LA ALEACION O MUY CERCANA A ELLA. EL AREA DEL ASIENTO EN LA SUPERFICIE SUPERIOR DEL DISCO DE LA VALVULA TIENE PROPIEDADES QUE IMPIDEN LA FORMACION DE INDENTACIONES, EN FORMA DE UN LIMITE ELASTICO (R P0,2 ) DE AL M ENOS 1.000 MPA A UNA TEMPERATURA DE APROXIMADAMENTE 20õ C, POR MEDIO DEL PROCESO DE DEFORMACION TERMOMECANICA, Y POSIBLEMENTE UN TRATAMIENTO TERMICO QUE AUMENTA EL LIMITE ELASTICO.
