摘要

Abstract

We described the methods of combined hardening of the surface of samples made of die steel grade 3Kh2V8F. To this end, the samples were exposed to thermal-chemical treatment—boroaluminizing, and the resulting diffusion layer was modified by the method of pulse beam treatment using an electron source with a plasma cathode. The study aims to investigate local structural-phase transformations of the boride diffusion layers due to high-speed heating by a millisecond duration electron beam. The diffusion layer structures after boroaluminizing and subsequent pulse beam treatment were compared. In addition, microhardness and surface topography were studied, and the phase state of the diffusion layer was assessed before and after electron beam treatment.
