Diamond Tools in Metal Bonds Dispersion-Strengthened with Nanosized Particles for Cutting Highly Reinforced Concrete

摘要

The paper describes two bonds dispersion-strengthened with WC and ZrO_2 nanoparticles, which are used in the manufacture of diamond tools for cutting reinforced concrete. The pattern of nanoparticles distribution in the metal matrix is studied. Physical-mechanical and tribological properties of the bonds have been determined. The use of dispersion-strengthened bonds is demonstrated to ensure a 60% longer tool life without reducing the cutting speed.
