| Summary: | Заглавие с экрана In the present work, mechanical and tribological studies of samples of Cu-Fe system with different content of steel in the copper matrix were carried out. Heterogeneous samples containing 10, 25, 36 and 50 % of steel 321 in the C11000 matrix were obtained by double wire-feed electron beam additive technology. Changes in the deformation behavior of the samples were shown, which can be explained by the presence of copper hardening by introducing steel into the composition. Tribological tests revealed a significant decrease in the average friction coefficient, which is observed mainly in samples containing 50 % of steel. This is due to a smaller role of friction setting and plastic displacement of specimen material from the friction contact zone when steel is introduced. Changes in mechanical properties of materials with increasing steel content up to 50 % mainly consist in a significant increase in ductility. |
