Description
Изобретение относитс к производству материалов высокой твердости, а именно к производству композиционных материалов , содержащих алмаз, кубический нитрид бора, бор и их смеси, и может быть применено в приборах и инструментах с направленным механическим воздействием, отводом тепла и др.The invention relates to the production of materials of high hardness, namely to the production of composite materials containing diamond, cubic boron nitride, boron and mixtures thereof, and can be used in instruments and tools with directed mechanical action, heat removal, etc.
Целью изобретени вл етс повышение анизотропии свойств композиционного материала и улучшение его механических свойств.The aim of the invention is to increase the anisotropy of the properties of the composite material and to improve its mechanical properties.
Поставленна цель достигаетс тем, что материал со структурой алмаза используют в виде поликристаллов цилиндрической, призматической, пластинчатой форм и размещают их равномерно в порошке неалмазного материала сло ми с одинаковой ориентацией каждого поликристалла в . Поликристаллическое строение материала со структурой алмаза обеспечивает боnfifl пппмнпе м жйг.ткпй Гчйм г. ппмпимишThe goal is achieved in that the material with the diamond structure is used in the form of polycrystals of cylindrical, prismatic, lamellar forms and they are placed uniformly in the powder of non-diamond material in layers with the same orientation of each polycrystal. The polycrystalline structure of the material with the diamond structure provides bonfif pppmnpe m zhig.tkpy gchym gpppmish

The use of polycrystals with a diamond structure instead of diamond powder in a composite material can significantly reduce the volume and length of the binder layers, make diamond - diamond type bonds and, as a result, determine
