Abstract
The process of modifying of boron- and aluminum diffusion layers properties on the surface of 5KhNM die steel by pulsed electron beam processing using an electron source with a plasma cathode based on a low-pressure arc discharge is considered. It was shown, using optical microscopy and electron backscatter diffraction methods, that the increase in the mechanical properties (microhardness and wear resistance) of the boroaluminized layer after electron beam processing is associated with a grain refinement and a phase redistribution, during which a concentration of the solid phase Fe2B occurs on the surface of the layer. It was found that the maximum microhardness on the surface of 5KhNM steel increases from 800 to 1400 HV and wear resistance improves by two times after electron beam processing.
期刊介绍：
Journal of Surface Investigation: X-ray, Synchrotron and Neutron Techniques publishes original articles on the topical problems of solid-state physics, materials science, experimental techniques, condensed media, nanostructures, surfaces of thin films, and phase boundaries: geometric and energetical structures of surfaces, the methods of computer simulations; physical and chemical properties and their changes upon radiation and other treatments; the methods of studies of films and surface layers of crystals (XRD, XPS, synchrotron radiation, neutron and electron diffraction, electron microscopic, scanning tunneling microscopic, atomic force microscopic studies, and other methods that provide data on the surfaces and thin films). Articles related to the methods and technics of structure studies are the focus of the journal. The journal accepts manuscripts of regular articles and reviews in English or Russian language from authors of all countries. All manuscripts are peer-reviewed.
