Abstract

FIELD: metallurgy. SUBSTANCE: iron-base sintered alloy has the following qualitative and quantitative composition, mas. nickel 3-6; copper 3-6; titanium 0.1-0.2; boron 1.7-2.3; manganese 8-10; nitrogen 0.08-0.12; the balance, iron. Iron-base sintered alloy is produced by mixing components, molding and sintering at temperature of 1200 C. Nitrogen is introduced in form of nitride of one or several alloy components. EFFECT: higher hardness. 1 tbl

Description

Изобретение относится к порошковой металлургии, а именно к производству сплавов на основе железа, которые могут быть использованы, например, в машиностроении. The invention relates to powder metallurgy, in particular to the production of iron-based alloys, which can be used, for example, in mechanical engineering.

Известен сплав на основе железа следующего состава, мас. никель 3,0-6,0; медь 3,0-6,0; титан 0,1-0,3;бор 0,1-1,5; железо остальное. Твердость такого сплава 160-270 кгс/мм2.Known alloy based on iron of the following composition, wt. nickel 3.0-6.0; copper 3.0-6.0; titanium 0.1-0.3; boron 0.1-1.5; iron the rest. The hardness of such an alloy is 160-270 kgf / mm 2 .

Целью изобретения является повышение твердости сплава. The aim of the invention is to increase the hardness of the alloy.

Это достигается тем, что в состав сплава, содержащего никель, медь, титан, бор, железо, дополнительно вводят марганец и азот при следующем соотношении компонентов, мас. никель 3,0-6,0; медь 3,0-6,0; титан 0,1-0,3; бор 1,7-2,3; марганец 8,0-10,0; азот 0,08-0,12; железо остальное. This is achieved by the fact that manganese and nitrogen are additionally introduced into the composition of the alloy containing nickel, copper, titanium, boron, iron in the following ratio of components, wt. nickel 3.0-6.0; copper 3.0-6.0; titanium 0.1-0.3; boron 1.7-2.3; manganese 8.0-10.0; nitrogen 0.08-0.12; iron the rest.

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

Твердость сплава составит ≈300 кгс/мм2 для всех составов.The hardness of the alloy is ≈300 kgf / mm 2 for all compositions.

Порошки компонентов смешивают, формуют и спекают при температуре ≈1200оС. Азот вводится в состав сплава в виде нитрида одного или нескольких компонентов, входящих в состав сплава.The powders of the components are mixed, molded and sintered at a temperature of ≈1200 о С. Nitrogen is introduced into the alloy in the form of nitride of one or more components that make up the alloy.
