Nanostructuring of Surface Layers and Production of Nanostructured Coatings As an Effective Method of Strengthening Modern Structural and Tool Materials

摘要

The high efficiency of improvement of macromechanical characteristics of structural and tool materials by nanostructuring their surface layers or due to the application of nanostructured coatings has been theoretically and experimentally substantiated. A loaded solid is considered as a multilevel system in which the surface layers are an independent subsystem. Special attention was paid to the surface-layer (coating)-substrate system, in which a staggered distribution of normal and tangent stresses and related different-scale stress concentrators appears.
