Abstract
A method of making cemented titanium carbide base cutting tools with increased tool life is disclosed. Substantially unoxidized carbide and binder metal powders are ground to a sub-micron particle size in the presence of a low-boiling oxidation-inhibiting ingredient covering the particles of said powders. A low-boiling pressing aid is added. The ground powders are then subjected to air drying to evaporate said oxidation inhibiting liquid ingredient and the pressing aid consisting preferably of polyethylene glycol. After compacting the waxed ground particles to a predetermined configuration, the compact is first heated to volatize the wax at an appropriate temperature and critically in the presence of a nitrogen based atmosphere which may contain 0-10% H.sub.2. The dewaxed compact is then heated to a higher second temperature level for effecting sintering in the presence of a vacuum.
