چکیده
|
Different volume fractions (1.3,2.6,and 7.6 vol.%) of carbon nanotubes (cnts) were dispersed within 8y-tzp nanopowders. mixed powder specimens were subsequently processed by spark plasma sintering (sps) and effects of cnts on the sintering process of 8y-tzp/cnt composites was studied. maintenance of cnts through the sps process was confirmed using tem and raman spectroscopy. studies on the sintering profile of zirconia-cnt composites (z-xc composites) could,to some extent,clarify the effect of cnts’ volume fraction on the densification rates of z-xc composites. the specimen with the highest content of cnt (z-7.6c) showed the lowest sintering rate while it was unable to reach full density.
