Test bench for materials’ corrosion-fatigue properties investigation

Carrying out fatigue and corrosion-fatigue tests under cantilevered rotating sample bending in the reversal of stresses in various media:

- in the air under room temperature;

- in the corrosion liquid medium (with different chemical composition)

- under room and elevated temperature - up to 950С in the thermostatted tank;

- in gas-saturated ( Н2S; СО2) mineral media under room temperature and elevated temperatures.
