Description
Известны способы определени газов в металлах методом вакуул плавлени образцов, в основе которого лежит принцип извлечени газов с последующим анализом их различными способами.Methods are known for the determination of gases in metals by the method of vacuums melting samples, which is based on the principle of extraction of gases with subsequent analysis of them in various ways.
Особенность предлагаемого способа заключаетс в том, что он позвол ет определ ть содержание газов в локальной зоне образца, выбираемой фокусированным в точку пучком электронов с помощью масс- спектрометрического анализа.A feature of the proposed method is that it allows determining the content of gases in the local zone of the sample, selected by an electron beam focused on a point using mass spectrometric analysis.
Дл осуществлени способа анализа газов в металлах и металлокерамике используют масс-спектрометр и электронную пушку с фокусированным пучком электронов.For carrying out the method of analyzing gases in metals and cermets, a mass spectrometer and an electron gun with a focused electron beam are used.
Схема расстановки оборудовани приведена на чертеже.The equipment layout is shown in the drawing.
На полированный металлический образец 1, помещенный в полости электронной пушки 2, подаетс строго дозированный по времени и мощности импульс потока электронов, сфокусированного в точке. При этом водород выдел етс из металла расплавленного участка, и давление в электронной пушке, измер емое вакуумметром 3, повышаетс . За счет разности давлени в полости электронной пущки 2 и в камере анализатора 4 масс-спектрометра газ через открытый кран 5 впуска поступает в источник 6 ионов. В зависимости от количества газов в образце анализ можно производить при открытом или закрытом кране 7 откачки из камеры анализатора. Газы из полости электронной пушки и вакуумпроводов удал ютс через кран 8.A polished metal sample 1, placed in the cavity of the electron gun 2, is supplied with a strictly dosed in time and power pulse of a stream of electrons focused at a point. At the same time, hydrogen is released from the metal of the molten area, and the pressure in the electron gun, measured by gauge 3, increases. Due to the pressure difference in the cavity of the electron gun 2 and in the analyzer 4 chamber of the mass spectrometer, the gas through the open inlet valve 5 enters the ion source 6. Depending on the amount of gases in the sample, the analysis can be carried out with the valve 7 open or closed from the analyzer chamber. The gases from the cavity of the electron gun and the vacuum tubes are removed through the valve 8.
После анализа газа в одной точке пучок электронов перемещ,аетс в другую точку, и процесс повтор етс по мере необходимости.After analyzing the gas at one point, the electron beam is moved to another point, and the process is repeated as necessary.
