Automated analysis of the multiple cracking of nanocoatings according to the integral parameters

We identify the networks of cracks in zirconium nanocoatings and perform their quantitative analysis on the basis of processing of the available digital images. The behavior of defects is assessed according to the results of diagnostics of different stages of the process of deformation. It is shown that different stages of the fracture processes in the coatings correspond to their own integral parameters of the image. On the basis of the consecutive processing of the data on multiple surface cracking, we establish the principal regularities of the coalescence of individual defects and the fragmentation of the coating. It is shown that multiple defects in the material partially increase its deformation characteristics and lead to the “absorption” of the energy of elastoplastic deformation of neighboring areas. We also present the theoretical background and the experimental data.
