Force Analysis of the Stress-Strain State of the Surface Layer of Al2O3–TiC Ceramics with AlN and TiN Coatings

By using the methodology of computer engineering, we establish the regularities of the stress-strain state of the surface layer of Al 2 O 3 –TiC ceramics with AlN and TiN coatings under the action of force loads.We determine the specific features of the influence of AlN and TiN coatings on the character of changes in the stress intensity on the surfaces of structural elements participating in the formation of the surface layer of Al 2 O 3 –TiC-ceramics. The formation of microstructural stress concentrators on the boundaries of AlN and TiN coatings with the original ceramics is also detected.
