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, by weight. %: 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 хром, причем компоненты находятся при следующем соотношении, мас. %: карбид вольфрама 62,0-64,0; карбид титана 39,5-41,5; кобальт 3,0-3,5; хром 3,0-3,5.The technical result is achieved in that the hard alloy containing tungsten carbide, titanium carbide, cobalt, further includes chromium, and the components are in the following ratio, wt. %: tungsten carbide 62.0-64.0; titanium carbide 39.5-41.5; cobalt 3.0-3.5; chrome 3.0-3.5.

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