Features of using a zirconium nanocoating as a surface sensor during steel plastic deformation are analyzed. Brightness distribution for a crack–surface system is considered on the example of electron-microscope images, and the form of cracks in question within a nanocoating is studied. The surface of steel specimens with a zirconium nanocoating is examined by defectometry and analysis results are summarized for the form and dimensions of the crack-like defects identified.
