Description

Изоб,рете.иие может быть использовано машиитостроительных предори ти х. Известны способы получени  па ных соедиЧ1енш 1 , ири которых соединение .после пайки напревают. Дл  повышени  прочиости и тугоплавкости соеди1нени  по предлагаемому способу нагрев производ т е вакууме до температуры испареЕИЯ компонентов, ведущих к ох рупчива ию соединени . Способ основан на способности иопаренн  отдельных кОМпонентов нз п.рипо  в твердом состо нии. Соединение, па лое пр.ипоем , содержащим компоиенты с повышетьнон скоростью испарени  в вакууме (напрвмар, припой марки Пор-40 содержит кадмий, температура -начала испа-рени  265°С п-ри давлении мм рт. ст.) после пайки подвергают обработке при повышенной температуре (но ниже температуры плавлени  прило ) в глубоком вакууме до испарени  этих 1КО;Мпо;неитов. В процессе обработки компонент с высокой скоростью испарени , например кадмии, улету-ЧИваетс  из па ного соединени , что приводит к изменению состава припо  И поаыщению прачности па його соеди:не«и . Испарен-ие этих компонентов приводит, как правило, к повышенню температуры раопа  и расЩИ,рению диапазона рабочих температур в сторону повышени , прочность при повышенных температурах также увеличиваетс . Врем  обработки па ных соединений выбираетс  в зависи мОСти от коиструкц1ии па ных iHBOB, примен емых материалов, температурь: обработки, величи:ны вакуума и марки примен емого припо . Так, ;напрИмер, дл  припо  Пср-40 при температуре 300°С и вакууме мм рт. ст. врем  испарен.и  кадми  из па пюго соедииепи  составл ет 8-10 час, прочласть соединений при этом возрастает на 10-15% II расшир етс  диапазон рабочих температур в сторону повышени  па 30-50 С. Предлагаемый способ позвол ет увеличить прочность па тых соедш-шний при использовании припоев, широко примен емых в промынь ленности. Предмет и з о б р е т е н и   1.Способ получени  па ных соединений, при которОМ соединение после пайки напревают, отличающийс  тем, что, с целью повышени  прочности и тугоплавкости соедипен-и , нагрев производ т в вакууме до температуры испарени  компонентов, ведущих к охрупчива ию соедИ|нени . 2.Способ по п. 1, отличающийс  тем, что, с целью удалени  ИЗ припо  кадми , нагрев осуП1ествл ют до температуры 265-300°С, при давлении мм рт. ст. в течение 8-Ючог.Isob, rete.iie can be used by mechanical engineering principles. There are known methods for the preparation of paired compounds 1, and which the connection is made after brazing. In order to increase the strength and refractoriness of the compound according to the proposed method, the heating is performed under vacuum to the evaporation temperature of the components, leading to loose compounds. The method is based on the ability of individual pairs of individual components in the solid state. The compound, having a solder containing components with a higher vacuum evaporation rate (for example, Por-40 brand solder contains cadmium, the temperature — the start of evaporation is 265 ° C) and the soldering process at elevated temperature (but below the melting point of the application) in a high vacuum until these 1KO evaporated; Mpo; neite. In the course of processing, a component with a high evaporation rate, for example, cadmium, flies away from the steam compound, which leads to a change in the composition of the solder AND to a higher consistency of the paired connection: not. The evaporation of these components leads, as a rule, to an increase in the temperature of the raop and the protrusion, to the rhenium of the range of working temperatures upwards, the strength at elevated temperatures also increases. The processing time of the solder joints is chosen depending on the coordination of the iHBOB paired solids, the materials used, the temperature: the machining, the magnitude of the vacuum and the brand of solder used. So, for example, for solder Psr-40 at a temperature of 300 ° C and vacuum mm Hg. Art. the evaporation time and cadmium from the vapor mixture is 8-10 hours; the compound strength increases by 10-15% in this case. The working temperature range increases towards 30-50 ° C. The proposed method allows increasing the strength of the soldered compounds. -shny when using solders, widely used in industry. Subject and datum 1. Method for producing solder joints, in which the joint is soldered after brazing, characterized in that, in order to increase the strength and refractoriness of the compound, heat is produced in vacuum to the evaporation temperature of the components leading to an embrittling connection. 2. A method according to claim 1, characterized in that, in order to remove ITS by soldering, heating is carried out up to a temperature of 265-300 ° C, at a pressure of mm Hg. Art. for 8-yuchog.
