Abstract

Procedimiento para la oxidación y tratamiento térmico conjuntos de piezas a temperaturas £ 1300ºC en un recinto de tratamiento de un horno que contiene un gas neutro o un gas reactivo, por introducción o inyección de al menos un reaccionante oxidante a temperatura > 570ºC, caracterizado porque después de la transformación de la estructura de las piezas existente a temperatura ambiente en la estructura deseada para el tratamiento térmico se ajusta en el recinto de tratamiento una relación PH2O/PH2 tal que se sobrepase la línea FeO + H2 = Fe + H2O y se forme una capa de óxido de FeO < 10 ìm.
