This paper discusses the issues of normal load during burnishing by a wedge cylindrical tool that influences the surface hardening of the 1.3505 steel according to the criteria of microhardness and thickness of nanostructured layer. It has been established that burnishing with a normal force of 200 and 250 N provides formation of a nanostructured layer with a 4,3…5,5 µm thickness and a maximum microhardness of 1120…1170 HV0,05.

Keywords: nanostructure, surface layer, hardening, burnishing, wedge cylindrical tool, bearing steel.
