Highly efficient electrical discharge machining of yttria-stabilized zirconia ceramics with graphene nanostructures as fillers
(Elsevier, 2022-06-14)
Electrical-discharge machining (EDM) of advanced ceramics allows the miniaturization of parts with complex shapes. Since electrical conductivity is required, non-conductive ceramics need a conductive second phase. This ...

Mechanical and electrical properties of low SWNT content 3YTZP composites
(Elsevier, 2015)
Fully dense 3mol% Y2O3-ZrO2 (3YTZP) composites with low single wall carbon nanotube content (0.5, 1 and 1.5vol% SWNT) were prepared by colloidal processing and spark plasma sintering (SPS). SWNT were distributed at ceramic ...
