<p>A tungsten carbide ceramic material which cuts titanium alloys four to five times faster than cemented carbide, ceramic-coated cemented carbides or state-of-the-art ceramic cutting tools can be densified with or without applied pressure at temperatures below 1700oC. Grain growth inhibitors or sintering aids can be added to control grain size in the final product. The polycrystalline tungsten carbide ceramic can be formed into wear components having improved performance in comparison to cemented tungsten carbides in a variety of drilling, cutting, milling, and other wear applications.</p> |
