Изобретение относитс к области пайки в вакууме, восстановительной или защитной средах и может быть использовано дл изготовлени qoтовых панелей, различного рода теплообменников и р да других, прет имущественно тонкостенных конструкций , работающих при нормальных и повышенных температурах.The invention relates to the field of soldering in vacuum, reducing or protective media, and can be used to make qotovy panels, various kinds of heat exchangers and a number of others, which are prefabricated thin-walled structures operating at normal and elevated temperatures.
Припои, используемые дл пайки тонкостенных конструкций, кроме соответстви требовани м, вытекающим из -услови эксплуатации издели должны обладать малой эрозионной активностью по отношению к основному металлу. Последнему требованию обычно удовлетвор ют припои, построенные на базе системы медь-марганец-никель .Solders used for soldering thin-walled structures, in addition to meeting the requirements arising from the use of the product, must have low erosion activity with respect to the base metal. The latter requirement is usually satisfied by solders constructed on the basis of the copper-manganese-nickel system.
Известен припой, используемый дл -пайки нержавеющей стали, никел или никелевых сплавов, с одной стороны , и железа или низколегированных сталей, с другой, содержащий, вес.%:Known solder used for brazing stainless steel, nickel or nickel alloys, on the one hand, and iron or low-alloy steels, on the other, containing, in wt.%:
Марганец 23,8Manganese 23.8
Медь,20,54Copper, 20.54
Кремний0,87Silicon0.87
НикельОстальное Ш-И 2Nickel Else Sh-2
Присадка меди в предложенных количествах , позвол ет (в сочетании с варьированием марганца) существенно вли ть на температуру плавлени припо без значительных пдисадок бора и кремни и сохранить малое эрозионное воздействие припо на основной металл.The addition of copper in the proposed amounts allows (in combination with the variation of manganese) to significantly affect the melting point of solder without significant effects of boron and silicon and to maintain a small erosive effect of solder on the base metal.
Кроме того, такое количество меди необходимо дл уменьшени хрупкости припоев и па ных соединений и регулировани их температуры без увеличени эрозионного действи по отношению к основному металлу.In addition, this amount of copper is necessary to reduce the brittleness of solders and solder joints and to regulate their temperature without increasing the erosive effect with respect to the base metal.
Повышение коррозионной стойкости .сплавов достигаетс за счет введени хрома и алюмини , образующих на по .верхности, которые они легируют, защитную трудновосстановимую окисную пленку. Присадка молибдена измельчает зерно и стабилизирует прочностные свойства па ных соединений, одновременно несколько повышаетс их коррозионна стойкость. Введение в сплав бора повышает активность припо и улучшает его растекаемость по основному металлу. An increase in the corrosion resistance of the alloys is achieved by introducing chromium and aluminum, forming on the top of the surface, which they alloy, a protective hardly-recoverable oxide film. The molybdenum additive refines the grain and stabilizes the strength properties of soldered compounds, while their corrosion resistance somewhat increases. The introduction of boron in the alloy increases the activity of the solder and improves its flow through the base metal.
Примеры выполнени припоев.Examples of solders.
Химический состав, %%Chemical composition, %%
Припой №1 легко перерабатываетс в фольгу, проволоку, ленту. Припой №2 обработке давлением поддаетс значительно- хуже и используетс в ос мовном в виде порошка. Деформируемость припоев промежуточных составов варьируетс между крайними. Припоем указанных составов была проведена пайка элементов пластинчато-ребристых теплообменников при температуре 1120°С, времени выдержки при температуре пайки - 5 мин., вакууме - рт.ст. Элементы были испытаны на влагостойкость, устойчивость в атмосфере морской туман , грибостойкость. Коррозии образцов в этих услови х не обкаружено . В таблице приведены данные о прочности стыковых соединений на разрыв.Solder # 1 is easily processed into foil, wire, tape. Solder # 2 pressure treatment is much worse and is used in the form of a powder. The deformability of the solders of the intermediate compositions varies between extremes. Soldering of the above compositions was carried out soldering of the elements of plate-fin heat exchangers at a temperature of 1120 ° C, holding time at the temperature of soldering - 5 minutes, vacuum - Hg. The elements were tested for moisture resistance, resistance in the atmosphere of sea fog, mushroom resistance. Sample corrosion in these conditions is not encircled. The table shows data on the strength of butt joints in the gap.
