Claims (1)

Способ получения сверхтвердых композиционных материалов, включающий воздействие высокого давления и температуры на расположенные в контакте друг с другом слои связующего вещества и сверхтвердых материалов - например, алмаза, кубического нитрида бора или их смесей, при этом нагрев осуществляют направленным тепловым потоком через слой связующего вещества до температуры не ниже температуры его плавления, отличающийся тем, что нагрев осуществляют встречными тепловыми потоками - основным, направленным через слой связующего вещества, и дополнительным, направленным навстречу основному тепловому потоку, при этом в период времени с начала нагрева до начала пропитки мощностью дополнительного теплового потока составляет 15 - 75% от основного, далее мощность основного теплового потока снижают, а мощность дополнительного увеличивают до достижения равномерного прогрева обоими тепловыми потоками слоя порошков и связующего вещества выше температуры его плавления.A method of producing superhard composite materials, including the action of high pressure and temperature on layers of a binder and superhard materials located in contact with each other, for example, diamond, cubic boron nitride or mixtures thereof, the heating is carried out by directed heat flow through a layer of a binder to a temperature not lower than its melting point, characterized in that the heating is carried out by counter heat fluxes - the main one, directed through a layer of a binder, and up to additional, directed towards the main heat flux, while during the period from the beginning of heating to the start of impregnation, the power of the additional heat flux is 15 - 75% of the main one, then the power of the main heat flux is reduced, and the power of the additional heat is increased until the heating of both layers is uniform powders and a binder above its melting point.
