Abstract
The paper presents the results of studies of the effect of high-frequency (100 Hz) mechanical vibrations on microstructure and wear resistance of metal, deposited with PP Kh10R4G2S wire and OSTs45M flux. It established that when horizontal vibration is used, deposited metal solid solution, uniformly saturated with fine iron-chromium borides (FeCr)B, prevails in the structure. Homogeneous structure improves wear resistance by 2.0–2.5 times. 9 Ref., 1 Table, 5 Figures.
