Description

Изобретение относится к области металлургии, в частности к составам твердых спеченных сплавов на основе карбида вольфрама, которые могут быть использованы для изготовления резцов, фрез и другого инструмента.The invention relates to the field of metallurgy, in particular to compositions of solid sintered alloys based on tungsten carbide, which can be used for the manufacture of cutters, milling cutters and other tools.

Известен твердый сплав, включающий, мас.%: карбид вольфрама 66,0; карбид титана 30,0; кобальт 4,0 [1].Known hard alloy, including, wt.%: Tungsten carbide 66,0; titanium carbide 30.0; cobalt 4.0 [1].

Задача изобретения состоит в повышении твердости сплава.The objective of the invention is to increase the hardness of the alloy.

Технический результат достигается тем, что твердый сплав, содержащий карбид вольфрама, карбид титана, кобальт, дополнительно включает карбид циркония и цирконий, причем компоненты находятся при следующем соотношении, мас.%: карбид вольфрама 61,0-62,0; карбид титана 29,0-31,0; кобальт 3,0-4,0; карбид циркония 2,0-3,0; цирконий 2,0-3,0.The technical result is achieved in that the hard alloy containing tungsten carbide, titanium carbide, cobalt, further includes zirconium carbide and zirconium, and the components are in the following ratio, wt.%: Tungsten carbide 61.0-62.0; titanium carbide 29.0-31.0; cobalt 3.0-4.0; zirconium carbide 2.0-3.0; zirconium 2.0-3.0.

В таблице приведены составы сплава.The table shows the alloy compositions.

В составе сплава на основе карбида вольфрама компоненты проявляют себя следующим образом. Карбид титана и карбид циркония увеличивают твердость сплава, но несколько снижают его прочность. Цирконий не взаимодействует с карбидом циркония и выполняет связующую функцию. Кобальт, также являющийся связкой, препятствует возникновению трещин при механических нагрузках, обеспечивая при этом высокую твердость и износостойкость сплава.In the composition of the alloy based on tungsten carbide components manifest themselves as follows. Titanium carbide and zirconium carbide increase the hardness of the alloy, but slightly reduce its strength. Zirconium does not interact with zirconium carbide and performs a binding function. Cobalt, which is also a binder, prevents the occurrence of cracks under mechanical loads, while ensuring high hardness and wear resistance of the alloy.

Сплав может быть получен методом порошковой металлургии путем прессования смеси порошков в изделия с последующим спеканием в атмосфере инертного газа или в вакууме.The alloy can be obtained by powder metallurgy by pressing a mixture of powders into products, followed by sintering in an inert gas atmosphere or in vacuum.
