Description
Известны ciioco6b изготов.генн нераспы.л емых rasonor.ioxHie.neii путем прессовани порошков химически активных -металлов. Недостаток известных способов состоит в том, что тазопотлотители при этом имеюп небольшую сорбциони то емкость и недостаточную мехапнческуго прочность .Known ciioco6b for the manufacture of unsprayed rasonor.ioxHie.neii by pressing chemically active α-metal powders. A disadvantage of the known methods is that in this case, the tazoplotters have a small sorption capacity and insufficient mechanical strength.
В описываемом способе указанный недостаток уст)анен тем, что после прессовани газоноглотите-ть спекают в вакууме. Спекание производитс при температурах, не вызывающих потери по1)истостн газопоглотител . Газопоглотители изготовл ютс в ви.те пористых деталей из химически активных веществ, напримс титана, циркони , путем прессовани порошков под давлением пор дка 2 in на 1 слг п последуюп1его спекани в вакууме при 700-900° в течение 30 мин. Спекание в i5aкууме при таких температурах не вызывает потери -пористости газопоглотител , увеличивает сорбпионную емкость поглотител в )езультате исиользовани влени капилл рной конденсапии в порах и повьннает его механическую прочность.In the described method, this disadvantage is set by the fact that after pressing the lawn-absorbing material is sintered in vacuum. Sintering is performed at temperatures that do not cause losses through the 1) exhaust gas getter. Gas absorbers are manufactured in vi. Parts of porous parts from chemically active substances, such as titanium, zirconium, by pressing the powders under pressure of about 2 in 1 slag and subsequent vacuum sintering at 700-900 ° C for 30 minutes. Sintering in an i5a vacuum at such temperatures does not cause a loss in the gas-scavenger porosity, increases the sorption capacity of the scavenger as a result of the use of capillary condensation in the pores and increases its mechanical strength.
Способ может быть применен дл изготовлени газопог.тот)Г1елей в электровакуумных приборах.The method can be applied for the manufacture of gas pumping machines in electronic vacuum devices.
