Abstract
LAS PIEZAS DE ACERO SON TEMPLADAS POR MEDIO DE LA CARBURACION DE LA SUPERFICIE, SEGUIDA DEL ENFRIAMIENTO. LA CARBURACION SE REALIZA POR MEDIO DE UNA DESCARGA DE PLASMA AL VACIO, EN PRESENCIA DE HIDROCARBUROS GASEOSOS, A TENSIONES ENTRE 200 Y 2000 VOLTIOS, PREFERENTEMENTE ENTRE 300 Y 1000 VOLTIOS, Y PREFERENTEMENTE CON ADICION DE ARGON. EL PLASMA ES PRODUCIDO POR MEDIO DE ELECTRODOS ACCIONADOS EN VACIO, DE LOS CUALES EL CATODO SIRVE COMO SOPORTE DE LAS PIEZA DE TRABAJO, Y ES ACCIONADO POR IMPULSOS. PARA CONSEGUIR CON ELLO, TAMBIEN EN PIEZAS DE TRABAJO CONFORMADAS IRREGULARMENTE, UN TEMPLADO REGULAR Y PARA REDUCIR LA CORRIENTE DE MASAS DE CARBONO A) SE LLEVA A CABO LA CARBURACION, A UNA PRESION TOTAL ENTRE 14 Y 30 MBARES (1400 A 3000 PA), B) SE ELIGE LA DURACION DEL IMPULSO ENTRE 110 Y 10000 (MU)S (MICROSEGUNDOS), C) SE ELIGE LA DURACION DE LA PAUSA ENTRE 30 Y 10000 (MU)S Y D) LA POTENCIA MEDIA PROPORCIONADA A LA DESCARGA DE PLASMA, ES ANULADA TRAS LA TERMINACION DE LA FASE INICIAL, POR MEDIODE LA DISMINUCION DE LA DURACION DEL IMPULSO Y/O POR EL ALARGAMIENTO DE LA PAUSA, BIEN DE FORMA CONTINUADA O BIEN ESCALONADAMENTE, DE FORMA QUE EL CONTENIDO DE CARBONO EN LA SUPERFICIE REFERIDA, SIN INTERRUPCION DE LA ACCION DEL IMPULSO, NO TRASPASE EN NINGUN MOMENTO LA BARRERA DE SATURACION DE LA MATERIA PARA EL CARBONO, EN EL CAMPO DE LA AUSTENITA.
