| Shrnutí: | Title screen Features of the structure of R6M5 steel based coatings obtained by multiscan electron-beam fusion of a hardening composition in vacuum have been studied. It is established that the carbide subsystem of the hardened layer is characterized by a multimodal distribution of carbide particles with d1 = 3.8 µm, d2 = 0.65 µm, and d3 < 0.25 µm. The volume fraction of M6C secondary carbide and retained matrix austenite can be controlled within broad limits by varying thermal parameters of the electron-beam fusion. An increase in the retained austenite fraction in the coating leads to improved wear resistance due to the ? ? a' marten-site transformation during friction and the presence of dispersed secondary carbides inside the matrix grains.
