Abstract
PROCEDIMIENTO PARA ENDURECER, POR CEMENTACION, PIEZAS DE TRABAJO METALICAS. CONSISTE EN INTRODUCIR LAS PIEZAS EN HORNO A ALTA TEMPERATURA, EXPONIENDOLAS A LA ACCION DE UNA MEZCLA DE GAS CONTENIENDO CARBONO. EN DICHA MEZCLA DE GAS SE GENERANFLUCTUACIONES DE PRESION CON UN PERIODO MAS BREVE EN COMPARACION CON LA DURACION DE TRATAMIENTO TERMICO. LA MEZCLA DE GAS ESTA FORMADA DE UN GAS PORTADOR INERTE, UN GAS CONTENIENDO OXIGENO. LAS FLUCTUACIONES DE PRESION SE GENERAN POR MEZCLA ADITIVA PULSANTE DEL GAS SOPORTADOR INERTE Y-O DEL GAS CONTENIENDO CARBONO Y-O DEL GAS QUE CONTIENE OXIGENO A LOS RESTANTES COMPONENTES.
