Abstract
The experimental studies were carried out for the influence of the dry axial compression process' parameters on the physical and mechanical properties of the composite ceramic material ZTA (Al2O3– ZrO2, ZrO2 > 20 mass percent) with various nanosized ZrO2 powder content (within the range of 0‒4 mass percent). The dependence was defined of both the compact density and general physical and mechanical properties of the sintered samples on the pressing force, as well as of the samples' linear contraction on the pressing force in both pressing and radial directions. It was established that the increasing of the nano-sized ZrO2 powder amount in the initial batch mixture promotes the increasing both the compact's and sintered samples' densities, as well as it promotes the linear contraction decreasing of the samples in course of burning. Under the industrial production conditions the comparison of wear resistances was implemented for AL2O3‒ ZrO2 ceramic samples with various ZrO2 content, as well as with nano-sized ZrO2 additions.
