Abstract
Description
Изобретение относится к области порошковой металлургии и касается производства спеченных твердых сплавов на основе карбида вольфрама, которые могут быть использованы для изготовления резцов, сверл, фрез и другого инструмента.The invention relates to the field of powder metallurgy and for the production of sintered hard alloys based on tungsten carbide, which can be used for the manufacture of cutters, drills, mills and other tools.
Известен спеченный твердый сплав на основе карбида вольфрама, содержащий 3,0-20,0 мас.% сплава-связки, содержащего, мас.%: кобальт 20,0-75,0; молибден - до 5,0; ниобий - до 3,0 [1].Known sintered carbide based on tungsten carbide, containing 3.0 to 20.0 wt.% A binder alloy containing, wt.%: Cobalt 20.0-75.0; molybdenum - up to 5.0; niobium - up to 3.0 [1].
Задачей изобретения является повышение прочности сплава.The objective of the invention is to increase the strength of the alloy.
Технический результат достигается тем, что в спеченном твердом сплаве на основе карбида вольфрама, содержащем 80,0-82,0 мас.% карбида вольфрама и 18,0-20,0 мас.% связки, связка содержит, мас.%: молибден 48,0-50,0; ниобий 1,0-2,0, рений 10,0-12,0; кобальт 36,0-41,0.The technical result is achieved in that in a sintered hard alloy based on tungsten carbide containing 80.0-82.0 wt.% Tungsten carbide and 18.0-20.0 wt.% Binder, the binder contains, wt.%: Molybdenum 48 0-50.0; niobium 1.0-2.0, rhenium 10.0-12.0; cobalt 36.0-41.0.
В табл. 1 приведены составы сплава, а также предел их прочности при изгибе. В табл. 2 приведены составы связки.In the table. 1 shows the composition of the alloy, as well as the ultimate strength in bending. In the table. 2 shows the composition of the ligament.
Порошки компонентов сплава смешивают в указанных соотношениях, смесь прессуют под давлением 4,5-4,8 т/см2 и спекают в электропечах при температуре 1300-1330°С в вакууме в течение 7-9 ч. При спекании связка растворяет часть карбида вольфрама и плавится. В результате получают плотный материал, структура которого состоит из частиц карбида вольфрама, соединенных связкой.The powders of the alloy components are mixed in the indicated proportions, the mixture is pressed under pressure of 4.5-4.8 t / cm 2 and sintered in an electric furnace at a temperature of 1300-1330 ° C in vacuum for 7-9 hours. During sintering, the binder dissolves part of the tungsten carbide and melts. The result is a dense material whose structure consists of tungsten carbide particles connected by a binder.
