The porous Co-Cr-Mo alloy material are used as got-up active bones. The rapid prototyping technology is used to produce the bones' prototype that plans to be displaced. The molten mould casting technology, two kinds of padding granules and vacuum centrifugal infiltration foundry technology are used to produce porous Co-Cr-Mo alloy, the technical parameters of this method are studied in this paper. The experiment indicates that using this method can obtain porous Co-Cr-Mo alloy with good connectivity and hig...
