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 кальций, теллур, бор, медь при следующем соотношении компонентов, мас.%: углерод 2,0-3,5; марганец 20,0-24,0; кальций 0,0001-0,0003; теллур 0,001-0,003; бор 0,2-0,3; медь 2,4-2,8; железо - остальное.The technical result is achieved in that the wear-resistant alloy based on iron, containing carbon and manganese, further includes calcium, tellurium, boron, copper in the following ratio of components, wt.%: Carbon 2.0-3.5; manganese 20.0-24.0; calcium 0.0001-0.0003; tellurium 0.001-0.003; boron 0.2-0.3; copper 2.4-2.8; 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, бор обеспечивают повышенную твердость и износостойкость сплава. Теллур и бор стабилизируют карбиды. Кальций раскисляет сплав. Медь увеличивает прочность сплава, препятствует образованию трещин, образующихся при истирании.In the composition of the alloy, the components manifest themselves as follows. Manganese, boron provide increased hardness and wear resistance of the alloy. Tellurium and boron stabilize carbides. Calcium deoxidizes the alloy. Copper increases the strength of the alloy, prevents the formation of cracks formed during abrasion.

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.
