Abstract
Description
Изобретение относится к порошковой металлургии, в частности к составам шахты для получения сверхтвердых материалов, применяемых для изготовления лезвийного инструмента, для обработки сплавов на никелевой основе. The invention relates to powder metallurgy, in particular to the compositions of the mine to obtain superhard materials used for the manufacture of blade tools for the treatment of nickel-based alloys.
Цель изобретения - повышение износостойкости. The purpose of the invention is to increase wear resistance.
Достижение цели изобретения иллюстрируется примерами, приведенными в таблице. Achieving the objective of the invention is illustrated by the examples given in the table.
Шихта для изготовления сверхтвердого композиционного материала содержит размол спеченного твердого сплава ВК60М или ВК100М, ВК150М размером 0,5-1 мкм, кубический нитрид бора (КНБ) с размером зерна 10-40 мкм и 1-2 мкм, взятых в количествах, позволяющих получить структуру с наиболее плотной и равномерной укладкой частиц КНБ и частиц твердого сплава, горизонтальные слои армирующего высокомодульного (модуль упругости 3600-43000 кгс/мм2) волокна молибдена или вольфрама в виде проволоки 33-46 мм, порошок нитрида тантала (ТУ 6-09-112-75), мелкодисперсный, и металлическое связующее, а именно алюминий или марганец, хорошо смачивающие в расплавленном состоянии поверхность нитрида бора.The mixture for the manufacture of superhard composite material contains a grinding of sintered hard alloy VK60M or VK100M, VK150M with a size of 0.5-1 microns, cubic boron nitride (CBN) with a grain size of 10-40 microns and 1-2 microns, taken in quantities that allow to obtain the structure with the most dense and uniform packing of CBN particles and hard alloy particles, horizontal layers of reinforcing high-modulus (elastic modulus 3600-43000 kgf / mm 2 ) molybdenum or tungsten fibers in the form of a wire 33-46 mm, tantalum nitride powder (TU 6-09-112 -75), fine, and metallic some binder, namely aluminum or manganese, good wetting melt surface boron nitride.
Композиционный материал в виде режущих пластин изготавливали в графитовых стаканчиках-нагревателях в два этапа. Сначала вхолодную изготавливали прессовку из указанных компонентов при давлении 15 кбар, затем при давлении 15-20 кбар выдерживали при 800-1250оС 30-35 мин.Composite material in the form of cutting inserts was made in graphite cups-heaters in two stages. Cold-formed compact is first manufactured from the said components at a pressure of 15 kbar, and then under a pressure of 15-20 kbar maintained at 800-1250 ° C 30-35 min.
Резцы, изготовленные из пластин, испытывают при резании никелевых сплавов при скорости резания 28 м/мин. Фиксируют износ пластин по задней поверхности и определяют относительный износ (h3/L).Cutters made of plates are tested when cutting nickel alloys at a cutting speed of 28 m / min. The wear of the plates on the rear surface is recorded and the relative wear (h 3 / L) is determined.
Резцы, изготовленные из сверхтвердого композиционного материала, превосходят в несколько раз по стойкости резцы из известного сверхтвердого материала.
