Abstract
A comparative analysis of the effect of various nanoadditives on a matrix of zirconium dioxide partially stabilized with Y2O3 during hot pressing by electrosintering is given. The microstructure obtained with different compositions of nanoadditives and sintering modes is investigated. The features of the influence of various nanoadditives from Al2O3, WC and SiC on the microstructure and properties of the obtained materials are revealed. The possibility of using the obtained composite materials, taking into account the peculiarities of mechanical properties, as functionally graded materials is considered.
