METHOD OF MAKING TOOLS BY IMPREGNATING A STEEL SKELETON WITH A CARBIDE, NITRIDE OR OXIDE PRECURSOR

Method of making tools by compressing, e.g., steel particles into a porous skeleton, having high temperature strength and being penetrated by a continuous network of pores of total volume below 50 percent and by filling at least part of the pores with a non-metallic material that is substantially un...

Zusammenfassung:Method of making tools by compressing, e.g., steel particles into a porous skeleton, having high temperature strength and being penetrated by a continuous network of pores of total volume below 50 percent and by filling at least part of the pores with a non-metallic material that is substantially undeformable and harder than the skeleton at temperatures up to about 650 DEG C.
