Title:
腐食試験装置および腐食試験方法
Document Type and Number:
Japanese Patent JP7117134
Kind Code:
B2
Abstract:
To prevent the clogging of a gas introduction pipe even when a test solution has a high concentration of metal salt.SOLUTION: A corrosion test apparatus 1 according to the present embodiment is an apparatus for testing the stress corrosion cracking resistance of a metal material. A test solution 11 simulating a corrosive environment is contained in a test container 10. Stress is applied to a test piece 12 by a stress imparting device 13 in a state in which the test piece 12 made of a metal material is immersed in the test solution 11. The corrosion test apparatus 1 according to the present embodiment includes a humidity adjustment section 2, a test container 10 containing the test solution in a state in which the outside air is blocked, a gas introduction pipe 14 for introducing inert or corrosive gas into the test container 10, and a gas exhaust pipe 15 for exhausting the gas in the test container 10. The humidity adjustment section adjusts the humidity of the inert or corrosive gas to be equal to or higher than the critical humidity of the metal salt contained in the test solution.SELECTED DRAWING: Figure 2
