Regularities of stress-strain state of surface layer of Al2O3‒TiC-ceramics with AlN and TiN coatings under the action of force load are established using the methodology of computer engineering. The features of influence of AlN and TiN coatings on the nature of changes in the stress intensity in the surfaces of structural elements forming the surface layer of Al2O3‒TiC ceramics are determined. The formation of microstructural stress concentrators at the boundary of the AlN and TiN coatings with the initial ceramics is revealed.
The regularities of influence of AlN and TiN coatings on stress-strain state of Al2O3‒TiC ceramics structural elements, which forming its surface layer, under influence of heat flow are established. The formation of microstructural stress concentrators at the boundary of AlN and TiN coatings with the initial ceramics is revealed.
