Abstract

FIELD: powder metallurgy. SUBSTANCE: gas absorber is made from titanium-based powder alloy containing 20-35 wt % vanadium and 0.1- 0.5 wt % calcium. Its porosity ranges from 25 to 65%. To prepare such gas absorber, powder alloy is first rolled into tape and then caked. Packed density of powder alloy is 0.7-1.5 g/cu.cm. Absorber provides sorption velocity exceeding that of pumping off in known gas absorbers at least by a factor of 1.5. EFFECT: improved performance.

Claims (1)

Использование: получение нераспыляемого ленточного газопоглотителя с повышенной скоростью сорбции методами порошковой металлургии. Создание средств сверхвысоковакуумной откачки с предельным давлением ниже 10-1 0 Па. Сущность: нераспыляемый ленточный газопоглотитель изготовлен из порошкового сплава, содержащего, мас. %: ванадий 20 - 35, кальций 0,1 - 0,5, титан - остальное. Пористость газопоглотителя составляет от 25 до 65%. Ленточный газопоглотитель может быть сформирован в виде спирали. Для получения газопоглотителя порошковый сплав указанного выше состава прокатывают в ленту, а затем спекают. Насыпная плотность порошкового сплава составляет 0,7 - 1,5 г/см3. Изготавливаемый в соответствии с данным изобретением газопоглотитель обеспечивает скорость сорбции, не менее чем в 1,5 раза превышающую быстроту откачки известных газопоглотителей.Usage: obtaining a non-sprayable tape getter with an increased sorption rate by powder metallurgy methods. Creation of ultra-high vacuum pumping facilities with a maximum pressure below 10 -1 0 Pa. Essence: non-sprayable tape getter made of a powder alloy containing, by weight. %: vanadium 20 - 35, calcium 0.1 - 0.5, titanium - the rest. The getter porosity is from 25 to 65%. The tape getter can be formed in the form of a spiral. To obtain a getter, a powder alloy of the above composition is rolled into a strip and then sintered. The bulk density of the powder alloy is 0.7 - 1.5 g / cm 3 . A getter made in accordance with this invention provides a sorption rate of not less than 1.5 times the pumping speed of known getters.
