The obtaining of high-density specimens and analysis of mechanical strength characteristics of a composite based on ZrO(2)-WC nanopowders

The structures, processes of shrinkage, and phase composition of the compact system ZrO(2)-WC, obtained by hot pressing with the transmission of high current, are considered in the article. We found that as a result of compaction, the ZrO(2)-WC-ceramics have uniform density distribution, with the fo...

Descripción
Sumario:The structures, processes of shrinkage, and phase composition of the compact system ZrO(2)-WC, obtained by hot pressing with the transmission of high current, are considered in the article. We found that as a result of compaction, the ZrO(2)-WC-ceramics have uniform density distribution, with the following optimal mode consolidation values T = 1,350°C, P = 30 MPa and t = 2 min. These conditions allow us to achieve the best combination of ceramic properties by criteria density and strength.
