При нагружекии усилие на образцы 17 контролируют с помощью измерителей 15 деформации. За счет переменного сечени брусьев 5 и 11 деформаци их по всей длине не измеThe rods 4 and 10 are mounted on the loading device 9 and the end of the 3 ampoules 1. The specimens 17 are loaded through the rods 4 and 10 from the cylinder 7. With the loading and the force on the samples 17, they are controlled using strain gauges 15. Due to the variable cross-section of the bars 5 and 11, their deformation along the entire length cannot be changed

Then, ampoule 1 is introduced into a container with a corrosive medium and the working force is adjusted. During the exposure to the medium, the change in forces (deformations) in sample 17 is measured using strain gauges 15 and the time to failure.

устройство.device.

Устройство содержит ампулу 1 с окнами 2 дл поступлени в ампулу 1 коррозионной среды, установленную на одном из концов 3 ампулы 1 т гу 4 в 5 виде бруса 5 переменного сечени с выступами 6 и захватами 7, закрепленными на одной из поверхностей 8 выступов 6 бруса 5. Устройство содержит также нагружатель 9, закреплеины на втором конце ампулы 1, и св занную с нагружателем 9 т гу 10 в виде бруса 11 перемеггного сечени , аналогичного брусу 5, с выступами 12 и захватами 13, установленными на поверхност х 14 выступов 12, обращенных к поверхност м 8 выступов 6. Т ги 4 и 10 установлены так, что выступы 6 т ги 4 размещены между выступами 12 т ги 10. Участки брусьев 5 и 11 с максимальным д поперечным сечением a, расположены около мест креплений т ги 4 к ампуле 1 и т ги 10 к нагружателю 9. Кроме того, устройство содержит измерители 15 деформаций, установленине на поверхност х 16 выступов 12 бруса 11 противоположных поверхност м 14.The device contains ampoule 1 with windows 2 for entering corrosive medium into ampoule 1 mounted on one of the ends 3 ampoules 1 ton 4 in 5 bar form 5 of variable cross section with projections 6 and grips 7 fixed on one of surfaces 8 of projections 6 of bar 5 The device also contains a loader 9 fixed on the second end of the ampoule 1, and connected with the loader 9 tons of 10 in the form of a bar 11 of pereggegnogo section, similar to bar 5, with projections 12 and grippers 13 mounted on surfaces 14 of the projections 12 facing to the surface 8 protrusions 6. T gi 4 and 10 are installed so that the protrusions of 6 tons of gi 4 are placed between the projections of 12 tons of gi 10. Sections of bars 5 and 11 with a maximum cross section a of a are located near the attachment points of the pull 4 to the ampoule 1 and the pull 10 to the loader 9. Except In addition, the device contains strain gauges 15, not installed on the surfaces 16 of the projections 12 of the beam 11 opposite to the surfaces 14.
