Abstract

METODO DE ENDURECIMIENTO SUPERFICIAL DE ACEROS INOXIDABLES AUSTENITICOS POR NITRURACION. DICHO METODO COMPRENDE CALENTAR LA PIEZA HASTA UNA TEMPERATURA DE 480 A 496 C. DURANTE MEDIA HORA; A CONTINUACION SE REGULA LA ATMOSFERA EXISTENTE EN EL HORNO HASTA CONSEGUIR UN PORCENTAJE DE AMONIACO DISOCIADO DE UN 85-95 POR 100, PARA LO CUAL SE SUMINISTRA AMONIACO ANHIDRO Y AMONIACO DISOCIADO. POSTERIORMENTE SE CALIENTA DICHA PIEZA HASTA UNA TEMPERATURA DE 570 A 585 C Y SE VUELVE A AJUSTAR EL SUMINISTRO DE GAS AMONIACO PARA REDUCIR SU PORCENTAJE DE DISOCIACION EN LA ATMOSFERA A UN 65-75 POR 100. CON ELLO SE CONSIGUE UN ESPESOR DE CAPA NITRURADA DE 0,10 A 0,18 MM.
