Description
Известен способ защиты изделий от окислени при пайке и термообработке их в вакууме , при котором газы, выдел ющиес внутри камеры нагрева в течение цикла термообработки , удал ютс откачивающей системой.A known method of protecting products from oxidation during soldering and heat treatment in vacuum, in which gases released inside the heating chamber during the heat treatment cycle are removed by the pumping system.
Дл поглощени газов и повышени качества изделий предлагаетс внутреннюю поверхность контер 1нера металлизировать алюминием .In order to absorb gases and improve the quality of the products, the inner surface of the container 1ner is proposed to be metallized with aluminum.
Толщина сло алюмини зависит от объема контейнера. С увеличением объема контейнера увеличивают и толщину металлизированного сло .The thickness of the aluminum layer depends on the volume of the container. With an increase in the volume of the container, the thickness of the metallized layer is also increased.
Обрабатываемые издели , уложенные и жестко закрепленные на поддоне, помещают в контейнер. Контейнер закрывают крышкой и герметично заваривают. Герметичность заварки провер ют воздухом, подаваемым через отверстие в крышке под давлением 3-5 атм. Затем в это отверстие вставл ют щланг отProcessed products, laid and rigidly mounted on the pallet, placed in a container. The container is closed with a lid and hermetically sealed. The tightness of the welding is checked with air supplied through a hole in the lid under a pressure of 3-5 atm. Then a shlang from
баллона с аргоном и контейнер продувают. После продувки отверстие закрывают заглушкой и герметично заваривают; контейнер загружают в печь и нагревают до требуемой температуры. После выдержки его извлекают из печи. Остывший контейнер вскрывают.a balloon with argon and a container rinsed. After purging, the hole is closed with a plug and hermetically sealed; the container is loaded into the oven and heated to the desired temperature. After aging, it is removed from the furnace. The cooled container is opened.
Дл повторени процесса металлизированные поверхности обдувают песком и снова металлизируют .To repeat the process, the metallized surfaces are sandblasted and metallized again.
Контейнер может быть использован до 10 раз.The container can be used up to 10 times.
Предмет изобретени Subject invention
Способ защиты изделий от окислени при пайке и термообработке в герметичном контейнере , отличающийс тем, что, с целью поглощени газов и повышени качества изделий , внутреннюю поверхность контейнера металлизируют алюминием.A method of protecting products from oxidation during soldering and heat treatment in an airtight container, characterized in that, in order to absorb gases and improve the quality of products, the inner surface of the container is metallized with aluminum.
