Description

Предлагаемый способ состоит в том, что поверхности сердечника сообщают или сетчатый вид плетением , или посредством пробивани  сплошных поверхностей, т.-е. перфорированием (как в терке), так, что с одной стороны она приобретает шероховатую форму, облегчающую закрепление сло  окиси. Сам по себе такой способ закреплени  представл ет удобства лишь в случае благородных металлов (платина),так как во врем  покрывани  приходитс  много раз крыть одно и то же место данной поверхности, наращива  слой на слое и разогрева  катод после каждого покрыти  током или иным путем, дабы вызвать удаление воды и кислотного остатка с поверхности металла; в случае неблагородных металлов такой процесс недопустим вследствие их окисл емости в воздухе .The proposed method consists in that the surfaces of the core communicate either with a mesh look by weaving, or by piercing solid surfaces, i.e. perforation (as in a grater), so that on the one hand it acquires a rough form, facilitating the fixing of the oxide layer. By itself, this method of fixing is convenient only in the case of noble metals (platinum), since during coating it is necessary to cover the same place of a given surface many times, build up a layer on the layer and warm up the cathode after each coating by current or otherwise. in order to cause the removal of water and acid residue from the metal surface; In the case of base metals, such a process is unacceptable due to their oxidability in air.

На чертеже по сн етс  предлагаемый способ изготовлени  окисных катодов.The drawing shows the proposed method for the manufacture of oxide cathodes.

Сердечник катода с помещаетс  в замкнутый сосуд с трубками ., через которые пропускаетс  стру  водорода. Покрывание слоем окиси достигаетс  опусканием в стаканчик с раствором данной соли, расположенным на дне цилиндра с водородом , что можно осуществить, не вскрыва  цилиндр, посредством магнита или иным путем. Покрытый слоем раствора сердечник доводитс  затем до красного калени  индукционными высокочастотными токами, пропускаемыми через катушку , окружающую данную трубку . После прокала сердечник снова погружаетс  в стакан с раствором, и процесс повтор етс  до получени  достаточно плотного сло  окиси.The cathode core c is placed in a closed vessel with tubes through which a stream of hydrogen flows. Coating with an oxide layer is achieved by lowering it into a glass with a solution of this salt located at the bottom of a cylinder with hydrogen, which can be done without opening the cylinder, using a magnet or by other means. The core covered with a solution layer is then brought to red heat by induction high-frequency currents flowing through the coil surrounding this tube. After calcination, the core is again immersed in a glass with a solution, and the process is repeated until a sufficiently dense layer of oxide is obtained.
