Abstract
It is carried out a qualitative analysis of experimental indentation diagrams of topocomposites with coatings of titanium nitride and aluminum nitride, having substrates of aluminum alloy D16T. The reasons for obtaining the unloading curves of the indentation diagrams of the topocomposites under study – with a linear and nonlinear section of the end of the unloading curve characterizing the interfacial delamination along the coating-substrate interface are investigated. It is shown that the delamination mechanism in both topocomposites implements a linear dependence between the load and the depth of indentation. The high level of hysteresis losses of the aluminum nitride coating was established and explained. It is found that the nonlinear shape of the end of the unloading curves of the indentation diagrams of topocomposites with coatings of aluminum nitride is associated with solid-phase structural changes in the coating material. The connection between the diverse aspects of the material world, considered in this work on the example of a change in the structure of matter under the influence of mechanical forces, can serve as an example of the development of models for knowledge management.
