The diamond cutting tool with the metal matrix composite (MMC) dispersion-strengthened by nanoparticles

Новые алмазосодержащие материалы с дисперсно-упрочненными наночастицами связками
The conception of this direction consists in doping the metal binder with strengthening nanoparticles that are to simultaneously solve the following problems: — to change the chemical potential at the diamond–metal binder interphase via doping with reactive ability nanoparticles (an increase in the adhesion strength of a diamond grain to the binder); — to ensure dispersion strengthening of the metal binder by introducing nanoparticles into the volume of the grains, which results in the enhancement of hardness, strength, and impact resistance; — to ensure the doping at the grain boundary of binder by introducing nanoparticles, which results in an decrease in the friction coefficient in the cutting area. The technology for fabricating diamond-containing materials (including the functional gradient materials) with the binding dispersion-strengthened with nanoparticles has been developed. This technology has been implemented into the batch production of diamond segmented cutting wheels, drills, and rope saws for the building and stone working industries.
