Abstract

We determine the principal regularities of the stressed state of the surface layer of Al2O3–TiC ground ceramics under the action of combined loads. It is discovered that the force load compensates the thermal elastic strains but, at the same time, complicates the stressed state as compared with the action of loads of the same type. We clarify the role of combinations of structural elements, which form the surface of Al2O3–TiC ceramics, in the formation of unfavorable microstructural stress concentrators.
