Abstract

FIELD: powder metallurgy. SUBSTANCE: method involves mixing fullerene with powdery material and thickening the obtained mixture followed by diamond synthesis. Iron-containing composition is used as powdery material and diamond synthesis is carried out in hydrogen medium under atmospheric pressure, at 930-980 C. For mixing fullerene C60, ferrophosphorus and iron powders were taken preferably at ratio = 8:6:86. After thermic working material is thickened at 800-1000 MPa and hardened from 930-980 C to -50 C at cooling rate 600-900 deg/s. Structure of the obtained material is an iron matrix at porosity 2% thickened with cementite and phosphide inclusions and synthetic diamonds (size is 3-20 mcm) distributed in its. Pure diamonds can be isolated from matrix by dissolving method. EFFECT: simplified and economy method. 2 cl

Изобретение относится к порошковой металлургии и может быть использовано для получения из фуллерена алмазсодержащего материала, а также поликристаллических алмазов. Способ включает смешивание фуллерена с порошковым материалом и уплотнение полученной смеси с последующим синтезом алмаза. Способ отличается тем, что в качестве порошкового материала используют железосодержащую композицию, а синтез алмаза осуществляют в среде водорода при атмосферном давлении и температуре 930 - 930 oС. При этом для смешивания предпочтительно брать порошки фуллерена С60, феррофосфора и железа в соотношении 8: 6: 86. Материал после термообработки уплотняют при 800 - 1000 МПа и закаливают с 930 - 980 oС до минус 50 oС со скоростью охлаждения 600 - 900 град/с. Структура полученного материала представляет собой железную матрицу с пористостью 2 %, упрочненную цементитными и фосфидными включениями, с распределенными в ней синтетическими алмазами размером 3 - 20 мкм. Из матрицы могут быть выделены алмазы в чистом виде, например, методом растворения. Способ отличается простотой и экономичностью. Полученные данным способом материалы могут найти применение в качестве конструкционных, инструментальных (для режущего или волочильного инструмента) или абразивных, например, для обработки стекол и т.д.The invention relates to powder metallurgy and can be used to obtain from fullerene diamond-containing material, as well as polycrystalline diamonds. The method includes mixing fullerene with powder material and densification of the resulting mixture, followed by synthesis of diamond. The method is characterized in that an iron-containing composition is used as a powder material, and diamond synthesis is carried out in a hydrogen medium at atmospheric pressure and a temperature of 930 - 930 o C. Moreover, for mixing, it is preferable to take powders of fullerene C60, ferrophosphorus and iron in a ratio of 8: 6: 86. After heat treatment, the material is compacted at 800 - 1000 MPa and quenched from 930 - 980 o С to minus 50 o С with a cooling rate of 600 - 900 deg / s. The structure of the obtained material is an iron matrix with a porosity of 2%, hardened with cementite and phosphide inclusions, with synthetic diamonds 3–20 μm in size distributed in it. Pure diamonds can be isolated from the matrix in pure form, for example, by dissolution. The method is simple and economical. The materials obtained by this method can find application as structural, tool (for cutting or drawing tools) or abrasive, for example, for processing glasses, etc.
