Description
Предлагаетс способ пайки керамики с металлом с применением в качестве флюса трехокиси молибдена , паносимого на керамику в местах пайки. Суспензи флюса приготавливаетс из мелкозернистого поропика технической трехокиси молибдена (МоО;;), замешанnoii на воде или нптробинд,ере.A method of soldering ceramics with metal is proposed using molybdenum trioxide as a flux, panosome onto ceramics at soldering sites. The flux suspension is prepared from fine-grained poropik of technical molybdenum trioxide (MoO ;;), mixed with water or nptrobind, ere.
В качестве припоев могут быть использованы разнообразные серебр но-медные и некоторые другие припои с температурой плавлени от 600 до 1200°.A variety of silver-copper and some other solders with a melting point of 600 to 1200 ° C can be used as solders.
Процесс пайки ведетс в атмосфере технического водорода.The soldering process is carried out in the atmosphere of technical hydrogen.
При нагреве в атмосфере водорода трехокись молибдена частично диффундирует в , а затем восстанавливаетс до металлического молибдена. -В результате , на поверхности керамики образуетс тонка пленка молибдеиа , отличающа с хорошим сцеплением с поверхностью керамики. Пленка молибдена имеет сильно развитую поверх нос гь и хорошо смачиваетс расплавлеиным ирипоем . Дл исключени потемнени поверхности керамики, содержаn . окислы железл, прп нагревеWhen heated in a hydrogen atmosphere, molybdenum trioxide partially diffuses into and then reduces to metallic molybdenum. As a result, a thin film of molybdea is formed on the surface of the ceramic, which is characterized by good adhesion to the surface of the ceramic. The molybdenum film has a strongly developed nose and is well wetted by melt iridoy. To prevent darkening of the surface of ceramics, containing. iron oxides
в водороде свыше 800° процесс пайки необходимо вести по следующему in hydrogen above 800 ° the soldering process must be carried out according to the following
1.Пагрев смачиваемого узла. до 800° в водороде дл восстаповлени трехокисп молибдена.1.Pagrev wetted site. to 800 ° in hydrogen to restore molybdenum trioxide.
2.Переключение печи на нейтральную атмосферу (техипческий азот).2. Switching the furnace to a neutral atmosphere (technical nitrogen).
3.Л,альнейш11й подъем темиературы вплоть до плавлени прино в атмосфере азота.3. L, a further rise of temperature up to melting in a nitrogen atmosphere.
4.Охлаждение печн с (})ерой азота.4. Cooling furnace with (}) nitrogen nitrogen.
Пайка, проведепна по онисанному режиму, не вызывает потемнени керамики п не ухудшает ее электроизол ционных свойств.The soldering, carried out according to the on-mode, does not cause the ceramics to darken and does not impair its electrical insulating properties.
Предмет изобретени Subject invention
Способ пайки керамики с металлами твердыми припо ми, о т л ич а ю щ и и с тем, что в качестве флюса, обеспечивающего смачивание п)пноем керамики, иримен етсн водна суспепзи трехокисп молибдена, а процесс пайки ведетс в атмосфере техническогд водорода.The method of soldering ceramics with hard solder metals, which is of a kind with the fact that, as a flux providing wetting of p) with the sting of ceramics, water is suspended in molybdenum trioxide, and the process of soldering is carried out in an atmosphere of hydrogen technology.
