Description

Изобретение относится к области металлургии, в частности к составам сплавов на основе серебра, которые могут быть использованы для изготовления орденов, медалей, монет, ювелирных изделий.The invention relates to the field of metallurgy, in particular to compositions of silver-based alloys, which can be used for the manufacture of orders, medals, coins, jewelry.

Известен сплав на основе серебра, содержащий, мас.%: серебро 92,5; германий 0,5-3,0; медь - остальное [1].A known alloy based on silver, containing, wt.%: Silver 92.5; germanium 0.5-3.0; copper - the rest [1].

Задачей изобретения является получение сплава на основе серебра, устойчивого к окислению.The objective of the invention is to obtain an alloy based on silver, resistant to oxidation.

Технический результат достигается тем, что сплав на основе серебра, содержащий германий, медь, дополнительно включает золото и олово, причем компоненты находятся при следующем соотношении, мас.%: серебро 81,5,0-85,5; германий 2,0-3,0; золото 1,5-2,5; олово 5,0-7,0; медь 5,0-7,0.The technical result is achieved in that the silver-based alloy containing germanium, copper, additionally includes gold and tin, and the components are in the following ratio, wt.%: Silver 81.5.0-85.5; germanium 2.0-3.0; gold 1.5-2.5; tin 5.0-7.0; copper 5.0-7.0.

В таблице приведены составы сплава.The table shows the alloy compositions.

В составе сплава компоненты проявляют себя следующим образом.In the composition of the alloy, the components manifest themselves as follows.

Золото, олово и медь способствуют повышению твердости и прочности сплава. Германий замедляет процессы окисления. Сплав выплавляют в электропечах. В разогретый тигель вводят компоненты, расплавляют их и перемешивают. Разливку сплава производят в стальную изложницу.Gold, tin and copper increase the hardness and strength of the alloy. Germanium slows down the oxidation processes. The alloy is smelted in electric furnaces. The components are introduced into the preheated crucible, melted and mixed. The alloy is cast in a steel mold.
