Objective
TO DEVELOP NEW CARBIDE, NITRIDE AND CARBO-NITRIDE HARD METALS FOR CUTTING AND NON-CUTTING APPLICATIONS IN WHICH BOTH THE TUNGSTEN AND COBALT OF THE PRESENT WC-CO ARE REPLACED BY CHEAPER AND MORE ACCESSIBLE RAW MATERIALS.
THE EXPECTED BENEFITS OF THE RESEARCH ARE TO PROVIDE BETTER AND CHEAPER MATERIALS AND ABRASIVES FOR CUTTING APPLICATIONS, SUCH AS METAL CUTTING, METAL REMOVAL AND POLISHING, MORE EFFICIENT ROCK-CUTTING AND DRILLING, AND COAL CUTTING. IN NON-CUTTING APPLICATIONS, THE NEW HARD METALS WILL BE EXPLORED FOR WIRE-DRAWING DIES, METAL TUBE-DRAWING PLUGS, SEALS AND BEARINGS.
NEW INTERSTITIAL ALLOYS WHICH, FROM THEIR KNOWN CRYSTAL STRUCTURES AND CRYSTAL CHEMISTRY, ARE EXPECTED TO BE HARD AND STRONG, WILL BE PREPARED BY A VARIETY OF ROUTES. THEIR SINTERABILITY WITH DIFFERENT METAL BINDERS TO GIVE DENSE COMPACTS WILL BE EXPLORED. THE MECHANICAL PROPERTIES OF THE COMPACTS WILL BE MEASURED TO ASSES THE POTENTIAL SUITABILITY OF EACH MATERIAL IN CUTTING AND NON-CUTTING APPLICATIONS. FINALLY, SAMPLES OF THE MOST PROMISING MATERIALS WILL BE SUPPLIED FOR APPRAISAL BY INDUSTRIAL ORGANISATIONS ALREADY COLLABORATING WITH THE WOLFSON RESEARCH GROUP IN WORK ON NEW CERAMIC CUTTING TOOL MATERIALS (SIALONS).
THE FOLLOWING TYPES OF NEW INTERSTITIAL ALLOYS, WHICH HAVE BEEN CHARACTERIZED STRUCTURALLY AND WHICH FROM THEIR CRYSTAL CHEMISTRY ARE EXPECTED TO HAVE GOOD HARD METAL PROPERTIES, WILL BE EXPLORED:
- SYSTEMS SUCH AS FE-MO-N, CO-MO-N AND NI-MO-N, WHICH HAVE ISOSTRUCTURAL PHASES WITH B-MANGANESE METAL;
- Z-PHASE COMPACTS, CR-NB-N, WITH FE AS A BINDER;
S-MON AND THE CORRESPONDING CARBO-NITRIDE MO(C,N);
- MON IN METAL MATRICES, PRODUCED BY COMBINED REDUCTION AND NITRIDING OF FE AND NI MOLYBDATES;
- DISPERSIONS OF TIN IN FE MATRICES, BY NITRIDING THE INTERMETALLIC COMPOUNDS FE2TI AND FETI2;
- OTHER TERNARY NITRIDES IN THE FE-NB-N, AND NI-NB-N SYSTEMS
SUCH AS FENB4N4 AND FENB2N2 WHICH ARE LIKELY TO BE COMPATIBLE, WITH FE AS A BINDER.
