Annotation:
Investigated and compared are the microstructure and microhardness of the boride layers formed on the die steel X12MF, as a result of electron beam processing in vacuum. Layers of borides have uneven structure, they contain different phases and inhomogeneous distribution of physico-mechanical properties. The formed layers have heterogeneous structure combining solid and plastic components that reduce fragility of the boride layer. The study of the microhardness of the boride layers after pulsed and continuous electron beams boriding allows to make a conclusion about the possibility of using two methods of boriding for hardening cutting tools and other, experiencing a warm-up while operation process up to high temperatures without significant reduction in performance properties.
