Description

Изобретение относится к области черной металлургии, а именно, к составам износостойких сплавов, которые могут быть использованы в машиностроении.The invention relates to the field of ferrous metallurgy, namely, to compositions of wear-resistant alloys that can be used in mechanical engineering.

Известен износостойкий сплав на основе железа, содержащий, мас.%: углерод 2,0-3,5; марганец 15,0-24,0; титан 2,5-6,0; железо - остальное [1].Known wear-resistant alloy based on iron, 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, марганец, дополнительно включает кобальт и компонент из группы: церий, самарий, неодим, празеодим при следующем соотношении компонентов, мас.%: углерод 2,5-3,5; марганец 15,0-20,0; кобальт 15,0-20,0; компонент из группы: церий, самарий, неодим, празеодим 0,1-0,5; железо - остальное.The technical result is achieved in that the wear-resistant alloy based on iron, containing carbon, manganese, further includes cobalt and a component from the group: cerium, samarium, neodymium, praseodymium in the following ratio of components, wt.%: Carbon 2.5-3.5; manganese 15.0-20.0; cobalt 15.0-20.0; component from the group: cerium, samarium, neodymium, praseodymium 0.1-0.5; 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 и кобальт обеспечивают повышенную твердость сплава. Компонент из группы: церий, самарий, неодим, празеодим, раскисляет сплав.In the composition of the alloy, the components manifest themselves as follows. Manganese and cobalt provide increased alloy hardness. Component from the group: cerium, samarium, neodymium, praseodymium, deoxidizes the alloy.

Сплав выплавляют в электропечах и отливают в горячие (400-450°C) металлические формы, обмазанные огнеупорной глиной. Отливки отжигают при температуре 740-760°C. Износостойкость сплава увеличится на 5-7% в сравнении со сплавом [1].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. The wear resistance of the alloy will increase by 5-7% in comparison with the alloy [1].
