Production of Nanocomposite Tungsten Carbide Buttons by Mixing with Co and ZrO₂ Nanopowders

Abstract:

The production of nanocomposite tungsten carbide buttons was studied. Using the mechanically induced solid-state mixing technique, the nanopowders were mixed with Cobalt (Co) and Zirconium Oxide (ZrO₂). During the consolidation and manufacturing process, the nanocrystalline characteristics of the nanocomposite were improved by replacing Co with ZrO₂-2 mol% yttria (YO₃), and the average grain size was reduced to 23-49µm. With the advent of fast sintering techniques and the synthesis of nanocomposites from the consolidation of nanocomposite powders, full dense buttons with outstanding properties were produced. These buttons have a very high nano hardness value (24.41GPa) and a low Young's modulus (E) value (332.02 GPa).
