By doping Co and/or Fe or Mn or Zn or Ni in WC-Co nanocomposite, nanocrystalline cemented carbide with inhibited grain growth were obtained. XRD showed peaks characterizing WC and Co in case of WC-15 wt.% Co, but showed addition peaks characterizing some oxides of tungsten and cobalt with W metal in case of WC-10 wt.% Co and/or 5 wt.% Fe of Mn or Zn or Ni. The crystallite size of the prepared WC-15 wt.% Co and heat- treated at 1000 8C was in the range of 1.1-7.4 nm, while it was 12-50 nm for WC-Co containing Fe or Mn or Zn or Ni as detected from XRD. On the other hand, the particle size was in the range of 200-400 and 300-500 nm, respectively, as detected from TEM and SEM. |
