Description

Изобретение относится к области металлургии, а именно к составам износостойких сплавов на основе железа, которые могут быть использованы для изготовления деталей, работающих в условиях трения и повышенного износа.The invention relates to the field of metallurgy, and in particular to compositions of wear-resistant alloys based on iron, which can be used for the manufacture of parts operating under friction and increased wear.

Известен сплав, содержащий, мас.%: углерод 2,0-3,5; марганец 15,0-24,0; титан 2,5-6,0; железо - остальное [1].Known alloy containing, wt.%: Carbon 2.0-3.5; manganese 15.0-24.0; titanium 2.5-6.0; iron - the rest [1].

Задача изобретения состоит в повышении износостойкости сплава.The objective of the invention is to increase the wear resistance of the alloy.

Технический результат достигается тем, что износостойкий сплав на основе железа, содержащий углерод и марганец, дополнительно включает медь, рений и никель при следующем соотношении компонентов, мас.%: углерод 2,0-3,5; марганец 20,0-24,0; медь 2,3-2,9; рений 0,05-0,1; никель 0,5-1,0; железо - остальное.The technical result is achieved in that the wear-resistant alloy based on iron, containing carbon and manganese, further includes copper, rhenium and nickel in the following ratio of components, wt.%: Carbon 2.0-3.5; manganese 20.0-24.0; copper 2.3-2.9; rhenium 0.05-0.1; nickel 0.5-1.0; iron is the rest.

В таблице приведены составы износостойкого сплава на основе железа.The table shows the compositions of a wear-resistant alloy based on iron.

В составе сплава компоненты проявляют себя следующим образом. Марганец, углерод, никель обеспечивают повышенную твердость и износостойкость сплава. Никель, медь увеличивают прочность сплава. Рений препятствует образованию трещин.In the composition of the alloy, the components manifest themselves as follows. Manganese, carbon, nickel provide increased hardness and wear resistance of the alloy. Nickel, copper increase the strength of the alloy. Rhenium prevents cracking.

Сплав выплавляют в электропечах и отливают в горячие (400-450°С) металлические формы, обмазанные огнеупорной глиной. Отливки отжигают при температуре 740-760°С.The alloy is smelted in electric furnaces and cast into hot (400-450 ° C) metal molds coated with refractory clay. Castings are annealed at a temperature of 740-760 ° C.
