Abstract
SE PRESENTA UN METODO PARA UTILIZAR UN REVESTIMIENTO BASADO EN CARBONO AMORFO PARA AMPLIAR LA VIDA UTIL DE UN INYECTOR DE COMBUSTIBLE QUE TIENE UNA AGUJA QUE FUNCIONA DENTRO DE UN CUERPO DE VALVULA, TENIENDO LA VALVULA Y EL CUERPO SUPERFICIES DE ACERO SUJETAS A IMPACTOS REPETIDOS Y A UN CONTACTO DE FRICCION, DESLIZANTE A LO LARGO DE LA VIDA UTIL DEL INYECTOR. EL METODO COMPRENDE A) LA DISPOSICION, EN LAS SUPERFICIES DE ACERO DE LA AGUJA O DEL CUERPO, DE UN REVESTIMIENTO BASADO EN CARBONO AMORFO, IMPLANTADO, ESTABILIZADO, CON UN GROSOR DE 1-10 MICROMETROS; EL REVESTIMIENTO TIENE UNA BAJA TENSION INTERNA Y UN BAJO COEFICIENTE DE FRICCION INDEPENDIENTEMENTE DE LA HUMEDAD Y SE ESTABILIZA POR LA PRESENCIA DE HASTA UN 30% DE SU PESO DE MATERIAL DE FORMACION DE CARBURO SELECCIONADO ENTRE EL GRUPO DE SILICIO, TITANIO Y TUNGSTENO, Y B) EL ACCIONAMIENTO RAPIDO Y REPETIDO DEL INYECTOR DE COMBUSTIBLE EN PERIODOS DE TIEMPO DE 51,5 MICROSEGUNDOS PARA ACTUACIONES SIMPLES, EXPONIENDO DE ESTA FORMA LAS SUPERFICIES REVESTIDAS DE LA VALVULA A UN CONTACTO DESLIZANTE BASICAMENTE CONTINUO Y A LAS FUERZAS DE IMPACTO DE LA AGUJA DE 70000-200000 PSI, REALIZANDOSE EL ACCIONAMIENTO EN AUSENCIA DE COMBUSTIBLE LUBRICADO EN LAS SUPERFICIES REVESTIDAS, MEDIANTE LO CUAL SE REDUCE SIGNIFICATIVAMENTE EL DESGASTE POR TRANSFERENCIA ATOMICA DE LOS ATOMOS DEL REVESTIMIENTO A LAS SUPERFICIES CONCORDANTES DURANTE EL IMPACTO O EL CONTACTO DESLIZANTE. TAMBIEN SE PRESENTA UN METODO PARA FABRICAR UN INYECTOR DE COMBUSTIBLE CON UNA AGUJA DE VIDA UTIL AMPLIADA QUE TIENE SUPERFICIES DE IMPACTO Y DE FRICCION DESLIZANTE, NO TODAS ELLAS EXPUESTAS CUANDO SE MIRA DESDE UNA UNICA DIRECCION.
