Abstract

Un proceso para compactar neumáticamente e isostáticamente un compacto sinterizado para densificar el compacto en donde la superficie del compacto es oxidizada para formar una barrera de oxido impermeable al gas sobre dicha superficie antes de que el compacto se someta al proceso de compactaciones isostático neumático. La oxidacion de la superficie de compacto es preferiblemente lograda mediante el someter a vapor el compacto antes o después de la sinterizacion.
