Abstract

Przedmiotem zgłoszenia jest sposób wytwarzania stopu wolframowego o dużej gęstości, zgodnie z którym miesza się proszki wolframu, niklu i żelaza z dodatkiem proszku trójtlenku wolframu jako dodatku porotwórczego, mieszaninę poddaje się zagęszczaniu matrycowemu, a następnie spiekaniu w temperaturze od 1500 do 1560°C, w atmosferze wodoru. Stosuje się proszek trójtlenku wolframu, o wielkości cząstek od 10 do 20 µm, w ilości 0,4 - 1,5% wagowych, a spiekanie prowadzi się z przyrostem temperatury od 10 do 15°C/min.The subject of the application is a method of producing a high-density tungsten alloy, in which powders of tungsten, nickel and iron are mixed with the addition of tungsten trioxide powder as a blowing additive, the mixture is subjected to matrix compaction and then sintering at a temperature of 1500 to 1560 ° C, at hydrogen atmosphere. Tungsten trioxide powder is used, with a particle size of 10 to 20 µm, in an amount of 0.4 - 1.5% by weight, and sintering is carried out with a temperature increase of 10 to 15 ° C / min.
