Embodiment

[0013] In this embodiment, the above-mentioned test device is used to carry out indoor simulated accelerated corrosion tests of different metal materials. The simulated accelerated test is carried out in the test box 1, and different samples with a size of 100 × 200 × 3mm are hung on the sample holder 14. Turn on the inflation switch e to carry out inflation and stirring, add tap water into the water bath box 2, and use the temperature control switch h to control the temperature at 35°C, turn on the accelerator switch a, adjust the accelerator speed control knob b, and pass the accelerator concentration probe 6 And accelerator concentration controller 9 controls the concentration of accelerator at 0.05mol / L, after the test starts, monitor the concentration of accelerator through accelerator concentration probe switch c, and feed back to accelerator concentration controller 9 according to its change information to adjust adding Accelerator speed. According to the above steps, t...

Abstract

The invention belongs to the technical field of corrosion test, and relates to an analog accelerated corrosion test device. A ventilated baffle plate is arranged at the bottom of a cavity of a test box body of a square box-type structure; a corrosion solvent is filled in the cavity of the test box body; an accelerant concentration probe is arranged on the side wall of the upper middle part of thetest box body; a sample holder is transversely placed on the upper part of the cavity of the test box body; a test box cover plate is arranged at the top of the test box body; the test box body is placed at the middle position of a water bath body of an oblong box-type structure in a supported mode; tap water is filled in the outside space of the test box body in the cavity of the water bath body; a resistance wire serving as heating equipment is arranged in the side wall of the bottom of the water bath body; an accelerant concentration controller, an aeration quantity controller and an electronic temperature controller are combined into an integrated structure in an electric communication mode; and an accelerant is filled in an accelerant accommodating tank. The device has short test period, high material corrosion resistance evaluation speed and good effect, is favorable for popularization and application of new materials, saves the materials, and has low test cost.

Description

Technical field: [0001] The invention belongs to the technical field of corrosion research and testing, and relates to a simulated accelerated corrosion test device for quickly evaluating the corrosion resistance of metal materials in seawater. Background technique: [0002] In the marine environment, the corrosion behavior and changing rules of marine engineering materials and components are very complex. At present, the main method for evaluating their corrosion performance is the actual sea coupon test. The real sea coupon test method has the advantages of real environmental conditions, simple test, and relatively reliable results, but there are problems such as long test period, uncontrollable environmental factors and sample loss. The general test period ranges from half a year to more than ten years, which seriously restricts the rapid application of new materials and new processes in engineering. Therefore, it is necessary to establish an accelerated test device that...
