Description
Известные способы пайки сложнолегнрованных сталей и сплавов с применением защитной атмосферы из водорода не дают надлежащих результатов , вследствие отсутстви надежных способов осушеши и очистки водорода.The known methods of brazing of complexed steels and alloys using a protective atmosphere of hydrogen do not give adequate results, due to the lack of reliable methods of drying and purifying hydrogen.
По описываемому сиособу этот недостаток устран етс тем, что пайка жаропрочных сплавов, содержани х в своем составе элементы с большим средством к кислороду, например тнтан, бор, алюмннпГ, осуществл етс во фторированной атмосфере.According to the described method, this disadvantage is eliminated by the fact that soldering of high-temperature alloys, containing elements with a large means of oxygen, for example, tntan, boron, aluminium, in the composition is carried out in a fluorinated atmosphere.
На чертеже показана схема упаковки деталей дл пайки во фторированной атмосфере.The drawing shows the packaging of parts for soldering in a fluorinated atmosphere.
Изделие, подготовленное дл пайки, помеп1,аетс контейнере 1 на сетчатом поддоне 2. Предварительно на дно контейнера помещаетс фтористый aiMMOHHii 3 в количестве 0,5-1,0 г на 1 л объема контейнера. Контейнер 1 закрываетс свободно прилегающей крьппкой 4 и помещаетс в герметичный контейнер 5. К патрубку 6 герметичного контейнера 5 подводитс защитный газ; второй патрубок 7 служит дл отвода из контейнера воздуха и образующихс в начальной стадии нагрева газов, иосле чего патрубок перекрываетс .The product prepared for soldering, see 1, is placed in container 1 on the mesh tray 2. Previously, aiMMOHHii 3 is placed at the bottom of the container in the amount of 0.5-1.0 g per 1 liter of container volume. The container 1 is closed with a loosely attached jaw 4 and placed in a sealed container 5. A protective gas is supplied to the pipe 6 of the sealed container 5; the second pipe 7 serves to remove air from the container and the gases formed in the initial stage of heating, and then the pipe closes.
В качестве защитной среды могут примен тьс обычньп техническиГ водород или аргон.Conventional hydrogen or argon can be used as a protective medium.
Подготовленный контейнер помещаетс в нечь дл нагрева. При нагреве фтористый аммоний диссоциирует с образованием в конечной етадии смеси газов водорода, азота и фтористого водорода. Образующиес газы вытеси ют воздух из контейнеров. При этом на детал х образуютс слаболетучие фториды в виде тонкой пленки, преп тствуюн1ие окислению, а имеющиес металлические окислы переход т во (рториды.The prepared container is placed in the sun for heating. When heated, ammonium fluoride dissociates to form a mixture of hydrogen, nitrogen and hydrogen fluoride in the final stage of the study. The resulting gases force the air out of the containers. At the same time, non-volatile fluorides in the form of a thin film, preventing oxidation, are formed on the parts, and the available metal oxides are transferred to (rtorides.
Фторированна атмосфера позвол ет не только защитить от окислени , но и восстановить ранее окисленные жаропрочные материалы, обладающие очень устойчивыми окислами хрома, титана, алюмини и др., что вл етс особенно важным при пайке жаропрочными припо ми.Fluorinated atmosphere allows not only to protect against oxidation, but also to restore previously oxidized refractory materials that have very stable oxides of chromium, titanium, aluminum, etc., which is especially important when brazing with refractory solders.
Предмет изобретени Subject invention
Снособ иайкн сложнолегированных сталей и снлавов с применением защитной атмосферы, отличающийс тем, что, с целью осуществлени пайки жаропрочных сплавов, содержащих в своем составе элементы с больщим сродством к кислороду, например титан, бор, алюминий , пайку осуществл ют во фторированной атмосфере.The method of iacc alloyed steels and cathodes using a protective atmosphere, characterized in that, in order to solder heat-resistant alloys containing elements with a greater affinity to oxygen, such as titanium, boron, aluminum, soldering is carried out in a fluorinated atmosphere.
