The invention discloses a
metal material tensile stress
electrochemical corrosion liquid tank device and a method thereof. A
corrosion test tank is a coverless transparent cuboid-shaped acrylic expandable box body, and a
corrosion test tank is a coverless transparent cuboid-shaped acrylic expandable box body, and is connected with the top of a clamp by screws. Samples with different gauge lengthscan be immersed by adjusting the height of a
liquid tank through the sliding between a sleeve shell and the
liquid tank, the bottom end of the liquid tank is provided with a hole groove, and a fittingis cooperated to carry
out stress corrosion experiments on samples with different shapes. In addition, every box body is provided with a corrosion
liquid injection hole and an output hole to achievedynamic change of the corrosive environment. The novel corrosion liquid tank device and the method thereof have the advantages of realization of the in-situ electrochemical and tensile property detection of tensile samples with different shapes and different sizes under stress,
erosion and corrosion coupled action, convenience in disassembling and assembling, easiness in cleaning, quickness and accurateness in providing a test result,
elimination of the limitation of the sizes of the samples, reduction of the process re-optimization cost, and increase of the production efficiency.
