Abstract
Hybridization is a promising method for core/shell particles by a mechanical shock process
involving dry blending and dry impact blending. In this paper, hybridization was used to prepare
TiB2/Ni ceramics/metal and TiB2/Al2O3 ceramics/ceramics core/shell particles. The mechanism of
the formation and the features of the core/shell particles were analyzed. The nano- Al2O3 particles
can be coated on the surface of micron TiB2 particles directly by hybridization, The sub-micron
Al2O3 particles can be coated on the surface of micron TiB2 particles, only with the introducing of
PE-wax as transition layer. The mechanical properties of cermet sintered from TiB2/Ni core/shell
ceramics/metal particles were compared with that from TiB2/Ni blended particles.
