摘要
We establish the main regularities of the stressed state of the surface layer of ground Si3N4–TiC ceramics under the action of combined loads. We also reveal specific features of the formation of structurally inhomogeneous stresses and microstructural stress concentrators affecting the structure of the ceramics as a result of the formation of discontinuities.
