Abstract
Description
Изобретение относится к области металлургии, в частности к составам антифрикционных сплавов на основе олова, которые могут быть использованы для заливки подшипников.The invention relates to the field of metallurgy, in particular to compositions of antifriction alloys based on tin, which can be used for pouring bearings.
Известен также сплав на основе олова, содержащий, мас.%: сурьма 0,5-20,0; медь 0,2-10,0; олово и неизбежные примеси остальное [1].Also known is an alloy based on tin, containing, wt.%: Antimony 0.5-20.0; copper 0.2-10.0; tin and inevitable impurities 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 там, что сплав на основе олова, содержащий сурьму и медь, дополнительно содержит эрбий и титан при следующем соотношении компонентов, мас.%: сурьма 7,5-8,5; медь 12,0-13,0; эрбий 0,003-0,004; титан 0,005-0,01, олово остальное.The technical result is achieved there that the tin-based alloy containing antimony and copper additionally contains erbium and titanium in the following ratio of components, wt.%: Antimony 7.5-8.5; copper 12.0-13.0; erbium 0.003-0.004; titanium 0.005-0.01, the rest is tin.
В таблице приведены составы сплава.The table shows the alloy compositions.
Повышение износостойкости сплава достигается за счет комплексного влияния компонентов, входящих в его состав.Improving the wear resistance of the alloy is achieved due to the complex effect of the components included in its composition.
В структуре сплава присутствуют кристаллы β-твердых растворов сурьмы в олове, имеющие форму куба и обеспечивающие повышенную твердость, а также кристаллы химического соединения меди с оловом в виде мелких игл и эвтектики. Эрбий и титан способствуют образованию мелкокристаллической структуры сплава.The structure of the alloy contains crystals of β-solid solutions of antimony in tin, having the shape of a cube and providing increased hardness, as well as crystals of the chemical compound of copper with tin in the form of small needles and eutectics. Erbium and titanium contribute to the formation of a crystalline alloy structure.
