Abstract

PROCEDIMIENTO PARA LA CEMENTACION DE PIEZAS METALICAS MEDIANTE SU EXPOSICION AL INFLUJO DE UNA MEZCLA GASEOSA QUE CONTIENE CARBONO, A LA CUAL SE AÑADEN PULSATILMENTE UNO O VARIOS COMPONENTES GASEOSOS PORTADORES DE CARBONO. CARACTERIZADO PORQUE LA APORTACION DE LOS COMPONENTES GASEOSOS QUE CONTIENEN CARBONO ES INTERRUMPIDA DESPUES DE VARIOS CICLOS, COMPUESTOS RESPECTIVAMENTE DE UNA FASE DE APORTACION PULSATIL DE GAS QUE CONTIENE CARBONO Y UNA FASE SIGUIENTE SIN APORTACION DE GAS CON CARBONO, Y NO ES REANUDADA HASTA QUE HAYA TRANSCURRIDO UNA LARGA PAUSA, EN COMPARACION CON LA DURACION DE UN CICLO; Y PORQUE LA CANTIDAD DE NITROGENO SUMINISTRADA POR UNIDAD DE TIEMPO SE ELEVA DURANTE LA APORTACION PULSATIL DE LOS COMPONENTES PORTADORES DE CARBONO.
