Developement of advanced ceramics with 2D nanomaterials for application in propulsion and braking systems in the aerospace industry
This draft proposes a systematic study on advanced zirconia composites with either graphene or boron nitride nanosheets, from their manufacture to their microstructural, mechanical and tribological characterization. The aim is to elucidate the mechanisms introduced by these two-dimensional nanostructures to improve the properties of the ceramic matrix. Composites with a tetragonal zirconia matrix doped with 3 mol% yttrium oxide (3YTZP, 3 mol% Yttria Tetragonal Zirconia Polycrystals), with different nanosheet contents will be processed. Special attention will be paid to the dispersion of these nanosheets in the matrix in order to achieve a homogeneous distribution among the ceramic grains, a key aspect to improve the properties of the composites. Sintering will be carried out in an electric discharge furnace (SPS, Spark Plasma Sintering), optimizing the conditions to achieve dense composites and, at the same time, avoiding deterioration of the nanostructures.
