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, by weight. %: 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 барий, теллур, медь, ниобий при следующем соотношении компонентов, мас. %: углерод 2,0-3,5; марганец 20,0-24,0; барий 0,0001-0,0003; теллур 0,001-0,003; медь 2,0-2,4; ниобий 0,6-1,0; железо - остальное.The technical result is achieved in that the wear-resistant alloy based on iron, containing carbon and manganese, further includes barium, tellurium, copper, niobium in the following ratio of components, wt. %: carbon 2.0-3.5; manganese 20.0-24.0; barium 0.0001-0.0003; tellurium 0.001-0.003; copper 2.0-2.4; niobium 0.6-1.0; 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, ниобий обеспечивают повышенную твердость и износостойкость сплава. Теллур стабилизирует карбиды. Барий раскисляет сплав. Ниобий и медь увеличивают прочность сплава, препятствует образованию трещин.In the composition of the alloy, the components manifest themselves as follows. Manganese, niobium provide increased hardness and wear resistance of the alloy. Tellurium stabilizes carbides. Barium deoxidizes the alloy. Niobium and copper increase the strength of the alloy, prevents the formation of cracks.

Сплав выплавляют в электропечах и отливают в горячие (400-450°C) металлические формы, обмазанные огнеупорной глиной. Отливки отжигают при температуре 740-760°C.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.
