| 摘要 |
The invention relates to powder metallurgy, more specifically, to composite material production methods, and can be used for the production of copper base binders for diamond tools used in construction industry and stone working. The copper binder comprises the following components (wt.%): copper (30-60), iron (20-35), cobalt (10-15), tin (0-10.5), tungsten carbide (0-20) and an alloying addition. According to the first variant the alloying addition is a nanopowder having a specific surface area of 6-25 m2/g, which is present in an amount of 1-15% wt. According to the second variant the alloying addition is a nanopowder having a specific surface area of 75-150 m2/g, which is present in an amount of 0.01-5% wt. The binder possesses a high wear resistance without the essential increase in the required sintering temperature, as well as high hardness, strength and impact toughness. |
