Abstract
The structural state in the zones of indentation and scratch testing of Ti–Al–Si–Cu–N gradient coatings has been studied using dark-field electron microscopy for analyzing the bending-torsion of a crystalline lattice. It has been found that the strength properties of a substrate, which determine the degree of plastic relaxation of the applied load, are important for modifying the structure of coatings. An increase in the bending of a crystalline lattice with respect to the undeformed state, heterogeneity, and anisotropy of its values with respect to the point and axis of applied load have been found for the material under the indenter top. The formation of strips of localized deformation, in which an increase in crystal sizes, a decrease in the bending of a crystalline lattice, and residual local stresses are observed, has been shown.
