| Popis: | In order to research the toughening effects of carbon nanotubes on 3Y-ZrO2 via different moulding methods. 3Y-ZrO2 and 3Y-ZrO2 with two kind of carbon nanotubes were prepared by compression moluding forming and gel-casting. And all of the green bodies were sintering at 1600°C in high temperature furnace. The X-ray diffraction and density of sintered bodies, microstructural of fracture surface and fracture toughness were characterized and analyzed. Results shown that gel-casting is better than compression about toughening 3Y-ZrO2 by carbon nanotubes. For gel-casting, the density is nearly the same and fracture toughness has been improved which is form 5.17MPa·m1/2 to 5.63 MPa·m1/2. For compression moulding forming, the density was reduced by the aggregation of carbon nanotubes. The fracture toughness can’t improve by carbon nanotubes. |
