Abstract:
We have studied the effect of the ratio between concentrations of zirconium dioxide (stabilized by CaO) and corundum on phase composition and mechanical properties of nanostructured CaO–ZrO$_{2}$–Al$_{2}$O$_{3}$ ceramic composites. The CaO–ZrO$_{2}$–Al$_{2}$O$_{3}$ composites sintered at temperatures typical of ZrO$_2$ are found to be characterized by the optimal microhardness/fracture toughness ratio at corundum content C$_{\mathrm{Al}_{2}\mathrm{O}_{3}}$ = 5%. These composites have a high flexural strength; their porosity, coefficient of friction, and wear are typical of those for CaO–ZrO$_2$ ceramics.
