dc.description.abstract | Graphene-based nanostructures, used as potential reinforcement in ceramic composites,
have a great tendency to agglomerate. This requires the use of homogenization techniques during
the powder processing, posing the need to evaluate how these techniques affect the microstructure
and the mechanical properties of the resulting composites. The influence of the processing route
on the properties of 3YTZP (3 mol % yttria tetragonal zirconia polycrystals) ceramic composites
with 10 vol % cost-effective GNP (graphene nanoplatelets) has been addressed. Four different
powder processing routines combining ultrasonic powder agitation (UA) and planetary ball milling
(PBM) in wet and dry media have been used and all the composites were densified by spark
plasma sintering (SPS). The mechanical properties at room temperature in the macroscale have been
assessed by Vickers indentations, four-point bending tests and the impulse-echo technique, while
instrumented indentation was used to measure the hardness and Young’s modulus at the nanoscale.
The application of dry-PBM enhances greatly the mechanical and electrical isotropy of the composites,
slightly increases the hardness and lowers the elastic modulus, independently of the application of
UA. The combination of UA and dry-PBM enhances the flexure strength by 50%, which is desirable
for structural applications. | es |
