Abstract

La pulvimetalurgia es un método efectivo para fabricar piezas de acero inoxidable ferrítico. El boro promueve la formación de fase líquida durante la sinterización a 1174o C. Se adicionó boro de 0.8-1.2% en peso y se añadió ferrocromo para prevenir perdida de cromo. Las muestras se compactaron a 700 MPa y se sinterizaron a 1150o C, durante 60 min en atmósfera de hidrógeno. La densidad se determinó por el método de Arquímedes, las muestras se analizaron en el microscopio electrónico de barrido. La densidad alcanzó 7.02 g·cm-3 cuando el contenido de boro fue de 1.2%, se observó disminución de porosidad. Concluyendo que adicionando boro se promueve la densificación.
