Abstract
<PICT:0967136/C6-C7/1> A sintered cermet comprising carbide particles such as titanium carbide, tungsten carbide, boron carbide or silicon carbide bonded by 0.01-1 part by weight of Al, Mg or Ti or mixtures of these, is formed by explosively compacting the powdered carbide and the metal in powdered or massive form in a tubular container and then sintering the compact above the melting point of the metal and below the temperature at which solid state sintering of the carbide occurs. As shown in Fig. 1, a powder mixture of the carbide and the metal, preferably finer than 200 mesh, is packed in a metal tube 1 which is sealed with metal plugs 3. A layer of detonating explosive 4 is wrapped around the tube 1 and the assembly is immersed in water where the explosive is detonated and the powder mixture is compacted. To form compacted tubes a metal tube is positioned concentrically within an outer metal tube and the powder is placed in the annulus between the two tubes, Fig. 2 (not shown). The explosive is again wrapped around the outside tube and the explosion is effected under water. In a further modification, Fig. 3 (not shown), only the carbide is packed into the container in powder form and the metal component is present as a sheath on the outer wall of the central tube and a liner for the inner wall of the outer tube so that the carbide powder is sandwiched between the metal component which penetrates into the carbide during compaction. The compact may be sintered in the assembly or removed prior to sintering. Examples are given of the formation of cermets of WC-Al sintered at 800 DEG C. in vacuum, SiC-Al sintered at 800 DEG C. in CO2, B4-CAl sintered at 800 DEG C. in CO2, TiC-Mg sintered at 700 DEG C. in air, TiC-Ti sintered at 1100 DEG C. with an acetylene torch. Specification 878,196 and U.S.A. Specification 3,093,521 are referred to.
