| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: mix includes abrasive filler and iron powder in % ratio of 75-85:15-25. Abrasive filler is produced of a mix of iron powder with non-ferromagnetic hard-alloy metals or their carbides or borides melted in graphite crucible. Hard-alloy metal is processed to reach 1100-1200 kg/mm2 hardness and obtain ferromagnetic properties, ground to 0.2-0.32 mm particle size and mixed with iron powder. ^ EFFECT: improved durability and wearing capacity of imitated soil. ^ 4 cl |
