Аннотация: 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 nanoparticles blocking influence on recrystallization). Besides, the internal thermotension and adheПоказать полностьюsion wear decrease at high speed cutting (especially for stainless steel) in comparision with base hard metals. The test results display that the modification through ultrafine particles enables to improve the main properties: tool fine -1,3-4-fold; wear resistance - 1,6 - 2 - fold; fracture toughness - 1,8-2-fold; transverse rupture toughness - at 25 - 50%.
