Description
Лужение оловом изделий из тугоплавких металлов, например вольфрама , тантала, молибдена, графита, не смачиваемых оловом при температуре до 250°, в обычных услови х не представл етс возможным. При более высокой температуре начинаетс окисление этих металлов.Tinning of articles made of refractory metals, such as tungsten, tantalum, molybdenum, graphite, not wetted by tin at temperatures up to 250 °, is not possible under normal conditions. At higher temperatures, oxidation of these metals begins.
Насто щее предложение позвол ет производить лужение деталей из тугоплавких металлов и графита.This proposal allows for the tinning of parts made of refractory metals and graphite.
Издели , покрытые оловом, могут быть легко спа ны на воздухе между собой и с металлами, которые легко поддаютс лужению (медью, железом и пр-).Tin-coated products can be easily sealed in air between themselves and with metals that can be easily tinned (with copper, iron, etc.).
Предлагаетс издели из тугоплавких металлов выдерживать в печи при температуре 1100- 1200° под вакуумом пор дка 10 мм рт. ст., а затем в этой же печи погружать в расплавленное олово, нагретое до той же температуры, ка короткое врем . При этом олово покрывает издели ровным прочным слоем. Издели , покрытые оловом, могут быть легко спа ны обычным способом с металлами, поддающимис облуживанию.It is proposed to hold products made of refractory metals in a furnace at a temperature of 1100-1200 ° under vacuum in the order of 10 mm Hg. Art., and then in the same furnace immersed in molten tin, heated to the same temperature for a short time. At the same time, tin covers products with an even durable layer. Tin-coated products can be easily sealed in the usual way with treatable metals.
Предмет изобретени Subject invention
Способ лужени оловом изделий из тугоплавких металлов, например вольфрама, тантала, молибдена и графита в вакууме, отличающийс тем, что дл обеспечени смачиваемости при гор чем облуживанпи издели помещают в вакуум 10 мм рт. ст. при температуре 1100- 1200°, а затем при этих же услови х погружают в ванну с оловом.The method of tinning products made of refractory metals, such as tungsten, tantalum, molybdenum and graphite in vacuum, is characterized in that, in order to ensure wettability during hot service, the product is placed in a vacuum of 10 mm Hg. Art. at a temperature of 1100-1200 ° and then under the same conditions, immersed in a bath with tin.
