Looping die corrosion fatigue test device

摘要

PURPOSE:To always analyze and manage a nitric acid concentration and a metal ion concentration of aqueous solution in a circulation system in an on-line information system and obtain the test device capable of performing a corrosion fatigue test in a stress-loaded state in parallel with a fatigue test. CONSTITUTION:A fatigue tester 3 and a specimen to be tested are allowed to be in a stress-loaded state and a corrosion fatigue tester 4 capable of performing a corrosion fatigue test is parallel provided in the circulation system of nitric acid aqueous solution in a loop type corrosion fatigue tester having the circulation system of the nitric acid aqueous solution provided with a nitric acid aqueous solution tank 1. Further, a nitric acid concentration automatic analyzer 5 and a metal ion automatic analyzer 6 are provided.
