Description

Изобретение относится к области черной металлургии, а именно к сплавам на основе железа, используемым для изготовления деталей, работающих в условиях трения и износа. The invention relates to the field of ferrous metallurgy, in particular to iron-based alloys used for the manufacture of parts operating in conditions of friction and wear.

Известен литой высокобористый сплав, содержащий следующие компоненты, мас. углерод 0,2 0,5; бор 2,1 3,5; кремний 0,15 0,6; марганец 1,5 - 6,0; кобальт 1,0 4,0; железо остальное. Твердость сплава 54-67 HRC. Known cast high boron alloy containing the following components, wt. carbon 0.2 0.5; boron 2.1 3.5; silicon 0.15 0.6; manganese 1.5 to 6.0; cobalt 1.0 4.0; iron the rest. The hardness of the alloy is 54-67 HRC.

Цель изобретения повышение твердости сплава. The purpose of the invention is to increase the hardness of the alloy.

Цель достигается тем, что в состав сплава, содержащего углерод, бор, кремний, марганец, кобальт, железо, дополнительно вводят хром при следующем соотношении компонентов, мас. углерод 0,8 1,2; бор 4,0 4,5; кремний 0,15 0,6; кобальт 1,0 4,0; хром 5,0 7,0; железо остальное. The goal is achieved by the fact that in the composition of the alloy containing carbon, boron, silicon, manganese, cobalt, iron, chromium is additionally introduced in the following ratio of components, wt. carbon 0.8 1.2; boron 4.0 4.5; silicon 0.15 0.6; cobalt 1.0 4.0; chrome 5.0 7.0; iron the rest.

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

Твердость сплава составит 70 72 HRC для всех сплавов. ТТТ1 The hardness of the alloy is 70 72 HRC for all alloys. TTT1
