Изобретение относитс к устройствам дл определени газов в металлах и может быть использовано при определении водорода в металлах и сплавах, содержащих летучие компоненты , способные взаимодействовать с ним при пониженных температурах с образованием гидридов.The invention relates to devices for determining gases in metals and can be used in the determination of hydrogen in metals and alloys containing volatile components capable of interacting with it at low temperatures with the formation of hydrides.
Известно устройство дл определени газов в металлах, содержащее реакционную трубку с тиглем и загрузочным устройством дл образцов, источник нагрева, вакуумную систему и газоанализатор. В реакционной трубке установлен подвижный зонд, окруженный снаружи охлаждающим устройством. Однако указанное устройство не может быть использовано в случае взаимодействи легколетучих компоиентов с анализируемым газом.A device for detecting gases in metals is known, comprising a crucible reaction tube with a sample charging device, a heating source, a vacuum system and a gas analyzer. A movable probe is installed in the reaction tube, surrounded outside by a cooling device. However, this device cannot be used in the case of the interaction of volatile components with the analyzed gas.
Известно также устройство дл определени кислорода и водорода в титане методом вакуум-плавлени , в котором дл устранени вли ни иаров титана на результат определени анализ образца проводитс с использованием угольных гильз. Выдел ющиес из образца водород и кислород (в виде окиси углерода) откачиваютс через стенки раскаленной гильзы, а превративщийс в карбид титаи полностью остаетс внутри гильзы. Однако при определении малых концентрацийA device for determining oxygen and hydrogen in titanium by the method of vacuum-melting is also known, in which, to eliminate the effect of titanium ions on the result of the determination, the analysis of the sample is carried out using carbon shells. The hydrogen and oxygen (in the form of carbon monoxide) released from the sample is pumped out through the walls of the heated tube, and the titanium carbide that is converted and remains completely inside the sleeve. However, when determining low concentrations
анализируемого газа (1 г металла и менее), встречающихс , напри.мер, в алюминиевых сплавах, указанное устройство не может быть применено, поскольку количество газа, выдел ющегос во врем анализа из угольной (графитовой) гильзы, превышает количество газов, выдел ющихс из анализируемого образца.of the analyzed gas (1 g of metal and less), found, for example, in aluminum alloys, the indicated device cannot be used, since the amount of gas released during the analysis from the carbon (graphite) liner exceeds the amount of gases released from analyzed sample.
Известно устройство дл определени газов в металлах, содержащее реакционную трубку с дном, загрузочное приспособление, источник нагрева. вак умную систему и аиал затор.A device for detecting gases in metals is known, comprising a reaction tube with a bottom, a loading device, a heat source. Vak smart system and aial congestion.
Недостатками известного устройства вл ютс низка чувств тельность и точность определени , а также плоха дегазаци металлов .The disadvantages of the known device are low sensitivity and accuracy of determination, as well as poor degassing of metals.
С целью повышени чувствительности и точности определени , а также улучшенн ;ieгазанин на дне реакционной трубки установлена канеула с двойными стенками, а над кансулой подвешен на тросике пористый колокол , размещенный между кансулы , образу с ними гидрозатвор, а также капсула выполнена пористо.In order to increase the sensitivity and accuracy of the determination, as well as improved; ie, the carbon dioxide pipe at the bottom of the reaction tube is double-walled, and a porous bell is placed on the cable above the cannula and placed between the cannula and the capsule, and the capsule is porous.
На чертеже изображено предлагаемое устpoiicTBO , продольный разрез.The drawing shows the proposed popiicTBO, longitudinal section.
Устройство дл определени газов в метал .тах и сплавах состоит из реакцлонной трубкнA device for determining gases in metals and alloys consists of a reactive tube.
