Аннотация: The influence of nanoparticles additives on the hard metals properties has been investigated. Nanoparticles introduced into a binder of average size decrease the metal interlayer and therefore increase the strength of binder and composite as a whole. The reduction of the carbide grain average size was found as well (owing to nanopaПоказать полностьюrticles blocking influence on recrystallization). Besides, the internal thermotension and adhesion wear decrease at high speed cutting (especially for stainless steel) in comparision with base hard metals. The test results display that the modification through ultrafme particles enables to improve the main properties: wear resistance - 1.6 - 2 - fold; fracture toughness - 1.8 - 2 - fold; transverse rupture toughness - at 25 - 50%; tool life - 1.3 - 4 - fold.
